Busy loop

[GoogleCodeExporter]

In the current code, the select call has a timeout of 0, which makes the
select return immediately.  It might be better to use the blocking form of
select (use NULL instead of giving it a pointer to a timeout of zero
seconds) or, even better, allow the user to give a pointer to a timeval to
use as the timeout for the select call.
