is there something like select(2) or poll(2) available in the
standard (HP) libraries? I hoogled around a little bit but didn't
find anything. (Something like this will be crucial for networking
stuff listening on v4 and v6 sockets at the same time)


A very basic thing to start from:
   http://code.haskell.org/~thielema/poll/
 It is still subject to change. We are planning to use this in alsa-seq.

  haskell lets you write more scalable code than C, but C's tools for

  locks and protected methods. The problem is, the only language I've
  found where that's true that *also* has reasonable tools to deal with
  scaling beyond a single system is Eiffel (which apparently abstracts
  things even further than haskell - details like how concurrency is
  achieved or how many concurrent operations you can have are configured
  when you start an application, *not* when writing it). Unfortunately,
  Eiffel has other problems that make it undesirable.

 I can't make a comparison, because I don't know Eiffel.

 I do, and I don't recognize what the OP is referring to - I suspect he meant
 Erlang.
