Description
Blocks the calling thread until the TLightweightSemaphore is in signaled state or until the specified timeout is over.
However, the blocking does not occur immediately. WaitFor first spends a few CPU cycles in a spin-loop and then blocks the thread if the semaphore is still not in the signaled state.
WaitFor returns a TWaitResult.
