- add PTHREAD_PID_DEBUG which prints the pid before each debuglog line
- output thread returned in pthread__next
- add asserts in pthread__sched akin to asserts in pthread__sched_bulk:
check if scheduled thread is at front/end of queue
- pthread__upcall: output event/interrupted LWP count instead of LWPid
of the first event/interrupted LWP (since unblock upcalls can have
multiple event LWPs).
- pthread__find_interrupted: output LWPid here
int pthread_attr_setcreatesuspend_np(pthread_attr_t *);
int pthread_suspend_np(pthread_t);
int pthread_resume_np(pthread_t);
needed for java. Approved and fixed by cl.
- prevent BLOCKED upcalls on double page faults and during upcalls
- make libpthread handle blocked threads which hold locks
- prevent UNBLOCKED upcalls from overtaking their BLOCKED upcall
this adds a new syscall sa_unblockyield

1. add new pthread__abort() and change pthread_assert(0) to it.
2. put constcond in the right place (in the macro).
3. no space after pthread__assert macro.
mangling results.
Fixes regression in test yield2, dating to 2003/1/2 when
pthread__locked_switch() was changed to not store the saved-context
pointer until after switching stacks.
Note to self: regression tests exist to be run.
over a sleep queue and puts everything on the run queue. This permits
the iteration to be inside the acquisition of the run queue spinlock,
avoiding repetitive acquire/release cycles.
* thr_create() (stub in libc aborts)
* thr_exit() (stub in libc calls exit())
* thr_yield() (stub in libc does nothing)
Also make the libc thr_self() stub not abort.
XXX Should we add thrattr_*() stubs for setting the detach-state?
