Yeah, that makes a massive difference. After I sent the message you quote, I
tried timing vfork()+execve(), and it's more than 100x slower than vfork()
alone. Not really surprising. I still think the staggering efficiency of
Unix vfork() is one of the wonders of the computing world, but maybe that's
not altogether relevant. :-)

All the same, you don't know it's going to be too slow until you've tried it
and it is.

It seems to me that spawning a new process for (on average) one out of six

Excessive ... in a good way? :-)
