-# You may prefer to use select for applications that have many threads
-# using one file descriptor, and poll for applications that have many
-# different file descriptors.  With USE_POLL poll() is called with at
-# least one pollfd per I/O-blocked thread, so 1000 threads sharing one
-# descriptor will poll 1000 identical pollfds and select would be more
-# efficient.  But if the threads all use different descriptors poll()
-# may be better depending on your operating system's implementation of
-# poll and select.  Really, it's up to you.  Oh, and on some platforms
-# poll() fails with more than a few dozen descriptors.
