[PATCH] semtimedop - semop() with a timeout
Patch from Mark Fasheh <mark.fasheh@oracle.com> (plus a few cleanups
and a speedup from yours truly)
Adds the semtimedop() function - semop with a timeout. Solaris has
this. It's apparently worth a couple of percent to Oracle throughput
and given the simplicity, that is sufficient benefit for inclusion IMO.
This patch hooks up semtimedop() only for ia64 and ia32.
