This is a bit improved version of Ted's diff:
* Add support of shared=1 for sem_init()
* Less memory leaks in error paths
* More strong checks where applicable
This is RFC/FYI status only, still under testing.

This may or may not be a working implementation of sem_open.
Using tricks similar to those used in shm_open, we create a semaphore
in a tmp file shared by mmap. This lets other processes share the
spinlock and counter. Our thrsleep and thrwakeup syscalls don't really
work between processes, so we
