For the next installation of 'difficult and painful network programming', I would like to do a non blocking socket open. My searches turned up any number of nodes on non-blocking reads and non-blocking socket accepts, but everyone seems to assume that if you're the one opening a socket, you're a client that can't do anythng until the server tells you to.

Forking isn't really an option, because some of the computers I"m connecting to will boot me after relatively short timeouts.

Essentially I want some code like this:


my @sockets;

foreach ( @hosts )  {
 push @sockets, IO::Socket->new(blah blah blah);
}

while ( 1 )  {
 foreach ( @sockets )  {
  if ( $_->exists && $_->is_open) {
   do_stuff($_); 
  }
 }
}

Does anyone know of a solution?
