There's `with-timeout' in timer.el, however (from the docstring):
The timeout is checked whenever Emacs waits for some kind of
external event (such as keyboard input, input from subprocesses, or
a certain time); if the program loops without waiting in any way,
the timeout will not be detected.
So it may not be exactly what you want.
