 I ran into a (possible) bug in Nagios OS X 10.5.4, which I tracked-down to
 poll() never timing out in the cmd file worker thread on that platform.
 It looks like poll() always returns 1, whether there is data on the pipe
 or not.  A quick fix that shouldn't break Nagios on other platforms and
 which doesn't require any configure checking of poll() is to manually
 pause if poll() returns 1 with an empty pipe.  You may want to use your
 poll() emulator, though.

 I have reported this to the Nagios-devel mailing list as well.
