How about my idea of creating a truncated file, the renaming it to the
table file. That keeps the table open for other open file descriptors,
but put a zero-length file in place in an atomic manner.
Fact is that the current code is really bad, so I request you do your
best, and let's get it in there for people to review and improve if
necessary.
