0.8.3.95.atropos.2
Rewrote the strange locking stuff in SUB-GC so that I can
understand it again: as a side effect, my newest thread/gc
torture test works again

OTOH, the final test in threads.impure.lisp was once observed
to break with this code, but who's to know if that's new?

0.8.3.95.atropos.1 ; cutting threads

There is getting to be rather a lot of sensible but
not-now-while-we're-releasing code in my thread/gc fix.
So here it is on a branch, hopefully minus the slightly
more evil debugging crud

doc/ - fix up some of the sgml errors that sourceforge keeps
mailing me about

New function release-spinlock that only changes the lock value
if we owned the spinlock, so good for unwind-protect cleanups
when lock acquisition failed

get-spinlock release-spinlock current-thread-id could all win
from being inlinable

Use a RT signal (SIG_DEQUEUE) for resuming threads that were
on queues, instead of having SIGCONT do both this and the
resume-after-gc task.

Scattered commentary describing the state of the signal mask
in various interesting places

In gencgc alloc, only install a deferred handler for GC if
there was no previous handler for anything else. This fixes
a longstanding bug where the GC thread would eat all cpu while
waiting indefinitely for othr threads to stop.

Add SIG_STOP_FOR_GC to the blockable list

interrupt_maybe_gc_int: enable signals before calling SUB-GC,
or the locking that sub-gc does is going to interact badly.

Minor rearrangement to parent thread to stop it having to wake
up on every GC

Inline arch_os_get_current_thread (note, thread.h is not a
sensible place for an x86linuxonly operation, rearrange this
before committing to HEAD)

Add grovel_headers lines for our RT signals. OAOOM alert...
(Actually, of these three we only need SIG-DEQUEUE)

0.8.3.95
Minimal fix to compile on Linux 2.6 and recent FreeBSD:
disable running of pre-gc hooks
move running of post-gc hooks later, so it is done after
other threads start running aagin, outside the GC lock

0.8.3.94:
Compiler fixes (touching only files in the alpha backend)
... the assembly routine for (signed-byte 32) [sic] truncate did
in fact work only for signed-byte 32 quantities, but was
being called on signed-byte 64 quantities. Fix it.
... the translators for ASH were broken in amusing ways: some
led to internal compiler errors when fed out-of-range
numbers; more insidiously, others allowed temporaries
to be overwritten in some cases. Fix them.
... lastly but not leastly, the %LI code to load an immediate
was wrong in a very small proportion of cases. After
much scribbling, deduce why and fix it.
... test cases to go with all of the above.

... make def-to-lisp emit CL:NIL, not just NIL.
... try to figure out what the solaris clause meant in

0.8.3.90:
Alpha build fix
... write a slightly more general PREPARE-ARGUMENT function for
modular arithmetic;
... as discussed on #lisp IRC 2003-09-24, post-0.8.4 we can optimize
common cases on platforms where register width and
bignum-element-width are the same.

0.8.3.87
After vast effort (mostly Christophe's) we have a fix for the
hangs in multithreaded CLX. Under some circumstances we could
be trying to scavenge one thread's stack using the stack
pointer from another: needless to say, this is not too effective.

When sleeping on a queue, loop around sigwaitinfo restarting
it until it stops returning EINTR
