If timing is critical, I would suggest use setitimer and
signal. This way, you'll have fairly accurate timing.
Register a SIGALRM handler with xforms, but use direct
handler to do your time sensitive stuff (but not xforms
stuff), then inform
the library using fl_signal_caught(). In the xforms
signal handler, you can do anything you want with xforms.
