* implement POSIX timersRich Felker2011-03-291-0/+1
| | | | | | | | this implementation is superior to the glibc/nptl implementation, in that it gives true realtime behavior. there is no risk of timer expiration events being lost due to failed thread creation or failed malloc, because the thread is created as time creation time, and reused until the timer is deleted.
* fix sem_open and sem_close to obey posix semanticsRich Felker2011-03-101-0/+1
| | | | | | | | | multiple opens of the same named semaphore must return the same pointer, and only the last close can unmap it. thus the ugly global state keeping track of mappings. the maximum number of distinct named semaphores that can be opened is limited sufficiently small that the linear searches take trivial time, especially compared to the syscall overhead of these functions.
* preliminaries to adding POSIX semaphoresRich Felker2011-03-031-0/+1
