Summary:                    [patch] Incorrect reloading of realtime peer causes
mailbox list to expand indefinitely
Description: 
Due to the current code's inability to short-circuit the reloading of a
realtime peer when it's looking for a user, the mailbox list is repeatedly
appended to.

For example, if you issue a 'sip show peer 1234', you may get something
like:
Mailbox     : 1234 at default

But after any inbound peer match (resulting in a call to find_peer), it
will result in:
Mailbox     : 1234 at default, 1234 at default

And so on, ad infinitum.

This can cause a large number of NOTIFYs to be sent to the peer, in some
cases resulting in a phone crash or reboot.

There may be other effects, but this is the observed behavior.
