According to the VMS documentation, when the image that creates a mailbox
deassigns the mailbox channel, the mailbox is deleted.  It has been my
experience that the mailbox remains until all processes which have
assigned a channel (for write) to the mailbox have closed their channels.

How can a process tell that the creator of the mailbox is gone (without
an exit handler and a special, predefined message?)  I checked the
io status byte, and the returned values look the same when a mailbox
is not being read but is still opened by the creator and when the mailbox
has been deassigned by the creator.

Please reply to me, I am not on the list.
