I did hear back from a couple of really hardcore FreeBSD developers on
the superpages fragmentation-during-fork() issue and their assessment
was that it was a known issue caused by contention for the pages
between the parent and child process between fork() and exec().
They (surprise, surprise) recommended the use of vfork() to workaround
the issue. So, as uncomfortable as that makes me, I guess it's the
right way to go, at least on FreeBSD.
Thanks!
