I just updated from CVS and tried this. when I subscribe to an extension
using Pulver Communicator (which is based on Messenger under the hood),
I get a continuous stream of subscriptions and subscription timeout
responses from asterisk.
I'm not sure why asterisk is telling Pulver that its subscription has
timed out, but of course it immediately tries again, and so on round in
very fast circles...

Real Programmers don't comment their code. If it was hard to write,
it should be hard to read, and even harder to modify.
These are all my own opinions.
