Bug#575731: [tex-k] tex/pdftex -recorder works incorrectly on parrallel TeX runs (race, breaks make -j)

Hi Vladimir,

You are surely right that other filename-related race conditions exist,
and that adding the pid to the temp file for fls is merely a palliative,
not a fix.  However, since that's the case that was reported, and since
it was easy to do, it seemed worth doing.  That's all.

Thanks,
Karl
