    Pardon me if I seem a little confrontational, I'm not the only one
    who sees clone() as costly. Also, compare these to Solaris thread
    creation and such, you'll find that solaris can do some pretty good
    stuff on a lowly machine. (Perish the thought!)

    On an Ultra at least, Linux fork()+exit()'s 3 times faster than
    Solaris even when lat_proc is run under strace. And it is a known
    fact that Solaris performs thread switches slower than normal process
    switches.
