| * | major improvements to cancellation handling•••- there is no longer any risk of spoofing cancellation requests, since
the cancel flag is set in pthread_cancel rather than in the signal
handler.
- cancellation signal is no longer unblocked when running the
cancellation handlers. instead, pthread_create will cause any new
threads created from a cancellation handler to unblock their own
cancellation signal.
- various tweaks in preparation for POSIX timer support.

| * | some preliminaries for adding POSIX timers | Rich Felker | 2011-03-29 | 1 | -0/+4 |
| * | remove useless field in pthread struct (wasted a good bit of space) | Rich Felker | 2011-03-28 | 1 | -1/+0 |
| * | implement robust mutexes•••some of this code should be cleaned up, e.g. using macros for some of
the bit flags, masks, etc. nonetheless, the code is believed to be
working and correct at this point.

| * | reorder mutex struct fields to make room for pointers (upcoming robust mutexes)•••the layout has been chosen so that pointer slots 3 and 4 fit between
the integer slots on 32-bit archs, and come after the integer slots on
64-bit archs.

| * | unify lock and owner fields of mutex structure•••this change is necessary to free up one slot in the mutex structure so
that we can use doubly-linked lists in the implementation of robust
mutexes.

| * | optimize pthread termination in the non-detached case•••we can avoid blocking signals by simply using a flag to mark that the
thread has exited and prevent it from getting counted in the rsyscall
signal-pingpong. this restores the original pthread create/join
throughput from before the sigprocmask call was added.

| * | fix and optimize non-default-type mutex behavior•••problem 1: mutex type from the attribute was being ignored by
pthread_mutex_init, so recursive/errorchecking mutexes were never
being used at all.
problem 2: ownership of recursive mutexes was not being enforced at
unlock time.

| * | use the selected clock from the condattr for pthread_cond_timedwait | Rich Felker | 2011-03-07 | 1 | -0/+1 |
| * | reorganize pthread data structures and move the definitions to alltypes.h•••this allows sys/types.h to provide the pthread types, as required by
POSIX. this design also facilitates forcing ABI-compatible sizes in
the arch-specific alltypes.h, while eliminating the need for
developers changing the internals of the pthread types to poke around
with arch-specific headers they may not be able to test.
