static int reallyBad = ENOMEM;
* Re-entrant errno.
* Each thread has it's own errno variable in pthread_t.
* The benefit of using the pthread_t structure
* instead of another TSD key is TSD keys are limited
* on Win32 to 64 per process. Secondly, to implement
* it properly without using pthread_t you'd need
* to dynamically allocate an int on starting the thread
* and store it manually into TLS and then ensure that you free
* it on thread termination. We get all that for free
* by simply storing the errno on the pthread_t structure.
* MSVC and Mingw32 already have their own thread-safe errno.
* #if defined( _REENTRANT ) || defined( _MT )
* #define errno *_errno()
* int *_errno( void );
* extern int errno;
if ((self = pthread_self ()).p == NULL)
* Yikes! unable to allocate a thread!
* Throw an exception? return an error?
