Hi Michael,
I'm familiar with that approach, having used it many times myself. The
choice of poll over select isn't important since they're basically the
same;
in fact, poll is sometimes implemented with select.
Who implements poll with select should suffer a fate worse than
death -- waking up a thousand sleeping threads to see if one
has some i/o ready is what poll was designed to avoid.
I think you're confusing a file I/O notification with mutual exclusion
and condition variables paradigm, another kind of IPC. The following
page provides necessary background information:

Besides, some select() implementations are actually poll()-based.
