Not so specifically at this point; it was a few years ago.  With a little
googling I did find this
(http://www.mail-archive.com/pld-cvs-commit%40lists.pld-linux.org/msg200381.html)
where Linux distribution maintainers were adding the .NOTPARALLEL directive
on their own to the 3.2.3 Makefiles.  They claim that the texi2XXX commands
(texi2dvi, texi2pdf) were not parallel-safe.
