suppress EINTR in sem_wait and sem_timedwait per POSIX, the EINTR condition is an optional error for these functions, not a mandatory one. since old kernels (pre-2.6.22) failed to honor SA_RESTART for the futex syscall, it's dangerous to trust EINTR from the kernel. thankfully POSIX offers an easy way out.
