The problem seems to be related to the global message index. When global indexing is disabled, the memory consumption stays in reasonable boundaries. I removed the global message index (global-messages- db.sqlite) and will see if it helps.

This caused Thunderbird to use massive amounts of memory (my system has 4GB, and nearly all was allocated to Thunderbird, with swap space well on the way to being full). Thunderbird froze. Subsequently, Thunderbird brought up the "a script on this page has stopped working" dialog. Even moving about a hundred emails at once causes large and noticeable memory use.
