Bug Description
This behavior began with upgrade to 12.04, no problems in 11.10.
strace reveals that the cpu is consumed by continuous polling.
Putting thunderbird "offline" stops the polling.

More info:
I disabled the global indexing and the enless spinning stopped.
I then removed the global index sqlite databases, restarted thunderbird and re-enabled the global indexing.
After rebuilding the index, all was well.
So in the end, I'm not sure if this was an event (i.e. corrupted database), an incompatibility between two versions of thunderbird, or a migration bug.
