#4509: System.Timeout inoperative with Data.IORef

Comment(by tibbe):
The I/O manager doesn't require there to be any registered file
descriptors to support timeouts. It uses a priority search queue to keep
track of timeouts and calls poll/epoll/kqueue with a timeout taken to be
the smallest timeout in the priority queue.
