Description:
Use signals for cpu profiling on Mac OS X
A while ago in r2315 Mac OS X cpu profiler implementation was changed to
pause
sampled thread instead of sending SIGPROF signal. That was done because at
that
point profiler send the signal to the whole process and it was handled on a
random thread. Now that signal-based implementation uses pthread_kill it may
well be used on Mac OS X too.
