The bug that was causing 1ea1646e6 in the first place was subtle, and
I wish I'd written down more detail about exactly why (I thought) it
was impossible to fix ...
Anyway, adding .NOTPARALLEL may be the right fix, but I can't see how
it will help unless we also revert 1ea1646e6. So at minimum you need
to send a revert commit as well.
Also we might need to add .NOTPARALLEL to po-docs/language.mk too.
Also it needs a big comment explaining exactly why we are doing this,
since what will inevitably happen later is someone will wonder why the
file has .NOTPARALLEL and try to remove it.
Rich.
