David Xu 8f0371f19d Fix name compatible problem with POSIX standard. the sigval_ptr and 
sigval_int really should be sival_ptr and sival_int.
Also sigev_notify_function accepts a union sigval value but not a
pointer.

David Xu 6cae59b1e7 Use TIMERS_UNLOCK. 2005-11-01 07:05:32 +00:00
David Xu 53bbdf8646 Add code to handle timer_delete(). The timer wrapper code is completely 
rewritten, now timers created with same sigev_notify_attributes will
run in same thread, this allows user to organize which timers can
run in same thread to save some thread resource.

While here, fix sleep() so that it is also a cancellation point (a
missing weak reference prevented that).

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.

Peter Wemm c5bfff3bab Use the recently exposed fs/gs set functions when compiling libthr to 
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.
