FWIW, I would have gone with a solution like that, say within
TestLib.pm's INIT. This ensures that any new future tests don't fall
into that trap again.

That does not sound really appealing.

I guess it depends on your requirements. Looking around I can see
some mention about flock() but it does not solve the problem at the
time the fd is opened. If this does not exist, then it seems to me
that we have very special requirements for our perl code, and that
these are not popular.
