Strange.  I just duplicated the problem ten minutes ago.  I wasn't
really expecting it, of course.  I'm feverishly trying to cause it to
fail again.  One thing that I noticed is that the bash command prompt
was returning prior to command execution.  That's usually an indication
of something being screwed up in the 'exec()' code.  Coincidentally
enough, that's what I've been working on for the last several months
"in my spare time".

I'm obviously doing something to improve things, though.  I wish I knew
what...

AFAICT, 1.1.5 is still as much as 18% slower than 1.1.4.  I don't know
when this happened.  I'm tracking this down, too.

Have you timed the build with 1.1.4 vs.  1.1.5, Earnie?  I suspect that
you'll see slower execution?
