/** @pred sleep(+ _Time_)
Block the current thread for _Time_ seconds. When YAP is compiled
without multi-threading support, this predicate blocks the YAP process.
The number of seconds must be a positive number, and it may an integer
or a float. The Unix implementation uses `usleep` if the number of
seconds is below one, and `sleep` if it is over a second. The WIN32
implementation uses `Sleep` for both cases.
