Very high resource usage

At the moment, I've had gwibber open for approximately seven hours. I have four accounts enabled: twitter, identica, facebook, and flickr. They're checked every five minutes.

According to System Monitor, gwibber is currently using 120.6 MB of RAM and, whenever it refreshes or sends a post, uses an entire core (50% of CPU). The window goes unresponsible (black and white for the compositing folks).

I haven't really looked into the internals of gwibber to understand just how it updates and sends posts.

This has been happening for the past two days. I think it could be related to the number of posts loading for the refresh (~150 follows on twitter, ~30 on identica, ~10 on flickr, ~700 on facebook but maybe one update every 10 minutes), but the send shouldn't block.

I am using the most current revision of trunk.
