Yes!  Why didn't I think of that before?  It's a little bit of a hack
since that pid could be reused, but the chances of that happening in
between write_or_exit pollings is obviously miniscule.  Way better.

I'll check it out. Incidentally, I want to rerun the glibc and gcc
testsuites.  I got some timeouts for some unknown reason before :).
If I just want to rebuild those targets, do I simply rm 066-glibc and
069-gcc and ./lfs -M?  I don't mind overwriting the installed files
and the build has already run to completion.  I think make will check
that all dependencies of the targets are built, right?
