[D-runtime] OS X unittest failure in core.sync.semaphore

[Sean Kelly]

The testWaitTimeout unittest is a bit of a hack in that it requires a signal to be sent from the main thread to a spawned thread within 100 milliseconds of an event occurring.  I chose this number based on experimentation, as I wanted it short enough not to hang up the unittest run for too long, but long enough that the test worked.  It appears that I left a bit too thin of a margin for your system.  I've increased the number to 200 milliseconds.  Hopefully that will be enough.  I'll check in the fix with the changes for issue 5488.
