I have a cunning idea (probably too cunning) to make the current code
work and I will hopefully be able to submit a short patch in a day or

Could you be more specific on how it doesn't solve the select problem
in when there are multiple processes writing on the pipe? As far as I
can tell, if (and its a big if) we can build something with threads
that works for a single process, it should work just as well for
multiple processes. Can you give an example sequence of writes and
selects that illustrates the problem? (Not that I think the thread
approach is without problems, I just can't see this one).
