No, on Posix systems we can delete the file, and it will be actually
deleted when its last handle is closed. I believe this works with
shared libraries as well.

No, I mean building Emacs with "make -j10 bootstrap".

It's the same problem, yes. Just a slightly different use case, which
could therefore have different probabilities for some aspects. For
example, the probability of the same .el file being recompiled from
two separate sessions is relatively small, except when you consider
the "make -jN" use case.
