On Unix, you can register a timeout callback function to be called when
select() times out. You can register the function to be called always - that
is - both when loads are going on and when the Library is idle, or you can
register it only to be called when the Library is waiting for a request.
Unfortunately you can only register one timeout function as select() doesn't
support more than this.
On Windows, it uses SetTimer() and I am not sure about if the functionality
matches - Eric?
