"Reconnecting" state consumes significant CPU/GPU resources

[metasim]

If a tab is left open with a Seahorse session running when the backend shuts down or disconnects, the "reconnecting" state consumes significant resources (I've accidentally drained a laptop battery this way).

Mostly just an annoyance, but seems like there might be a simple fix of making an overly tight polling or animation loop less aggressive, and save a few batteries in the process. :-)
