For rfork() specifically I've got code sitting around somewhere from a
thread library I wrote one weekend last year that implements most of
the applicable semantics under FreeBSD and Linux (i.e. stack splitting
and those flags that have a corresponding notion under Unix).  I
believe I have some Solaris code somewhere as well.  In the case of
DEC, one is better off implementing everything on top of Posix
threads, IIRC.
