Yeah, the joys of focusing on a single system... :-)

Unfortunately, that soltion only works for Linux and we want maximum
portability. It seems at least Solaris, OSF/1, HPUX and IRIX all support
defining FD_SETSIZE manually at compile time. I wonder why Linux/glibc broke
that ability...

But really, we need to:

1) swap how we work internally when poll() is around so that we won't have
    this problem on all systems that have poll() (= the majority)

2) deal with fd_set for the remaining select()-based systems, and it would
    probably involve a configure check for what method to use. And even then
    we can only give means on how to raise the bar, it would still need to be
    set to a compile-time fixed value.
