Looks like (file-select) is already a wrapper, but it appears to be a 
low-level one, ie: all the disadvantages of using C directly. And 
(port->fileno) will grab FDs.

The whole point of using select is to avoid threading. Still, IIRC 
chicken's threads are cooperative, so just call (file-select) with very 
small timeouts, and yield the thread. You can count the small timeouts 
to do a large timeout, or use (current-milliseconds).
