Details:

When changing auth port, which could happen at the request of another
process in a signal-like manner, unionmount does not reauthenticate
its handle to the mounted filesystem.  One way to fix this would be
to use a file descriptor instead of a port and let glibc handle the
reauthentication.

I can't help but think this issue has been overlooked in other translators
as well, so it might be a good idea to investigate this further before
closing this bug.
