Now, the first thread, the one using APR file, in the signal handler

the FD from the second thread! That is a problem that no locking of APR
file can solve. Any action on this FD will do things to the file from
the second thread, not from this one (because it's already closed).
But, by setting file->filedes to -1 before the close(), we can at least
mitigate the consequences of such a situation.
Ok, I got your point. It is not a threading issue. Its a signal handler
issue. For that purpose your proposal works just fine.
