as an aside, GvR added Windows' "spawn" API in 1.5.2,
so you can at least emulate some common variants of
fork+exec.  this means that if someone writes a spawn
for Unix, we would at least catch >0% of the uses with
~0% of the effort ;-)

fwiw, I'm more interested in the "unicode all the way
down" parts of the activestate windows project.  more
on that later.
