* If set, you can control the size of a thread's
* stack
* pthread_attr_getstacksize
* pthread_attr_setstacksize
*
* _POSIX_THREAD_ATTR_STACKADDR (not set)
* If set, you can allocate and control a thread's
* stack. If not supported, the following functions
* will return ENOSYS, indicating they are not
* supported:
* pthread_attr_getstackaddr
* pthread_attr_setstackaddr
*
* _POSIX_THREAD_PRIORITY_SCHEDULING (not set)
* If set, you can use realtime scheduling.
* Indicates the availability of:
* pthread_attr_getinheritsched
* pthread_attr_getschedparam
* pthread_attr_getschedpolicy
* pthread_attr_getscope
* pthread_attr_setinheritsched
* pthread_attr_setschedparam

* _POSIX_THREAD_PRIO_INHERIT (not set)
* If set, you can create priority inheritance
* mutexes.
* pthread_mutexattr_getprotocol +
* pthread_mutexattr_setprotocol +
*
* _POSIX_THREAD_PRIO_PROTECT (not set)
* If set, you can create priority ceiling mutexes
* Indicates the availability of:
* pthread_mutex_getprioceiling

* pthread_mutexattr_getprioceiling
* pthread_mutexattr_getprotocol +
* pthread_mutexattr_setprioceiling
* pthread_mutexattr_setprotocol +
*
* _POSIX_THREAD_PROCESS_SHARED (not set)
* If set, you can create mutexes and condition
* variables that can be shared with another
* process.If set, indicates the availability
* of:
* pthread_mutexattr_getpshared
* pthread_mutexattr_setpshared
* pthread_condattr_getpshared
* pthread_condattr_setpshared
*
* _POSIX_THREAD_SAFE_FUNCTIONS (set)
* If set you can use the special *_r library
* functions that provide thread-safe behaviour
*
* + These functions provide both 'inherit' and/or
* 'protect' protocol, based upon these macro
* settings.
*
* POSIX 1003.1c-1995 Limits
* ===========================
*
* PTHREAD_DESTRUCTOR_ITERATIONS
* Maximum number of attempts to destroy
* a thread's thread-specific data on
* termination (must be at least 4)
*
* PTHREAD_KEYS_MAX
* Maximum number of thread-specific data keys
* available per process (must be at least 128)
*
* PTHREAD_STACK_MIN
* Minimum supported stack size for a thread
*
* PTHREAD_THREADS_MAX
* Maximum number of threads supported per
* process (must be at least 64).

*
* PTHREAD_KEYS_MAX
* WIN32 permits only 64 TLS keys per process.
* This limitation could be worked around by
* simply simulating keys.
*
* PTHREADS_STACK_MIN
* POSIX specifies 0 which is also the value WIN32
* interprets as allowing the system to
* set the size to that of the main thread. The
* maximum stack size in Win32 is 1Meg. WIN32
* allocates more stack as required up to the 1Meg
* limit.
*
* PTHREAD_THREADS_MAX
* Not documented by WIN32. Wrote a test program
* that kept creating threads until it failed
* revealed this approximate number.

* The code here and within the library aims to work
* for all reasonable combinations of environments.
* For example, although the library itself can't be
* built (yet) in C, an application written in C can
* be linked and run against a library built using
* either WIN32 SEH or C++ EH.
*
* The three implementations are:
*
* WIN32 SEH
* C
* C++
*
* Please note that exiting a push/pop block via
* "return", "exit", "break", or "continue" will
* lead to different behaviour amongst applications
* depending upon whether the library was built
* using SEH, C++, or C. For example, a library built
* with SEH will call the cleanup routine, while both
* C++ and C built versions will not.
