Check for issues when other clients are active

Perhaps spurious <presence/> stanzas?

Nefit claim that maximum 5 clients can be connected simultaneously to one device

Good to know. I've seen some extra chatter occurring over the XMPP connection when a new client (for instance, the app) connects with the device while my lib is also connected, but up to now, it has worked without issues.

It might be that the issue that was raised (on GoT) might not actually be related to another client connecting, as I found that even with one connection, the backend sometimes stalls.
