    Still, though, there are legitimate applications wherein having multiple
    thousands of threads necessary. The most active IRC server on the net,
    from what I understand, is a FreeBSD Pentium which can accept ~1500 (this
    is from memory) connections.

    IRCD is a single-threaded application; threading it would be a very nice
    option (allows use of SMP facilities, etc.) If it is going to destroy its
    host machine by threading, however, then people aren't going to do it, or
    they're only going to do it on platforms which allow them to do it.

    A combo (clone<->lib) threading approach lets you do these sorts of things
    easily. Telling the IRC designers "You shouldn't support more than 1000
    connections per server" is kind of unrealistic, isn't it?
