It's necessary to avoid race conditions if you have multiple programs
that use the same units. E.g. `texutil.{o,ppu}` get opened (with
`O_TRUNCATE`) multiple times, rather than using atomic renames (which
would still be duplicate work ... but fpc is fast anyway. Still bad if
the compiler fails and `make` hasn't had a chance to clean up) or
locking.

I refuse to use `.NOTPARALLEL:` out of principle.

I can live with the other limitations - IMHO reasonable code won't do
*too* much of that, at least for things that `ppdep` even needs to
worry about.

Thanks for the quick response,
