Re: Fixing parallel byte-compilation

[Chad Brown]

I'll hazard a guess that this solves the `exact-same-time' problem,
but still leaves dueling emacs builds with potentially incompatible
.elc files if there's a multi-file change, and so it wasn't deemed
worth the trouble.  Of course, applying a patch someone already
wrote is less effort, so... :-)
