* Import my recent 1:1 threading working. some features improved includes:davidxu2005-04-0277-4641/+7200
| | | | | | | | | | | | | | | | 1. fast simple type mutex. 2. __thread tls works. 3. asynchronous cancellation works ( using signal ). 4. thread synchronization is fully based on umtx, mainly, condition variable and other synchronization objects were rewritten by using umtx directly. those objects can be shared between processes via shared memory, it has to change ABI which does not happen yet. 5. default stack size is increased to 1M on 32 bits platform, 2M for 64 bits platform. As the result, some mysql super-smack benchmarks show performance is improved massivly. Okayed by: jeff, mtm, rwatson, scottl

| | | | | | | run as a 32 bit support library for an amd64 kernel. 32 bit consumers of libthr have zero chance of running on an amd64 kernel since we don't implement the i386_set_ldt() family of functions. Note that this commit doesn't make it actually work, it just removes one more obstacle.

| | | | | | | | | | | | | | no userland locks are heald, the dead thread lock can no longer protect access to it. Therefore, instead of using an if (!dead)...else clause after walking the active threads list test the thread pointer before deciding not to walk the dead threads list. If the thread pointer is null it means it was not found in the active threads list and the dead threads list should be checked. 2. Do not free the stack of a thread that is not marked dead. This is the 2nd and final part of eliminating the race to free a thread's stack. MFC after: 3 days

* Close a race between a thread exiting and the freeing of it's stack.mtm2004-10-061-3/+2
| | | | | | | | | After some discussion the best option seems to be to signal the thread's death from within the kernel. This requires that thr_exit() take an argument. Discussed with: davidxu, deischen, marcel MFC after: 3 days

* The SUSv3 function say that the affected functions MAY FAIL, if themtm2004-09-221-27/+6
| | | | | | | | | | | | specified mutex is invalid. In spec parlance 'MAY FAIL' means it's up to the implementor. So, remove the check for NULL pointers for two reasons: 1. A mutex may be invalid without necessarily being NULL. 2. If the pointer to the mutex is NULL core-dumping in the vicinity of the problem is much much much better than failing in some other part of the code (especially when the application doesn't check the return value of the function that you oh so helpfully set to EINVAL).
