David Xu	a091d823ad	Import my recent 1:1 threading working. some features improved includes: ... 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	2005-04-02 01:20:00 +00:00
Jeff Roberson	bb535300dd	- Add libthr but don't hook it up to the regular build yet. This is an ... adaptation of libc_r for the thr system call interface. This is beta quality code.	2003-04-01 03:46:29 +00:00
