Having a non-invasive fix for this long-standing issue would be really
great, even if that means reducing the scope of systems where this can
be fixed.
The last time I poked at the bear (54fb8c7d), there was a test posted
by Alexander Lakhin that was really useful in making sure that
concurrency is correctly handled when a file is unlinked:

It worked with VS but not on MinGW. How does your patch react to this
test?
