[Bug 1039837] [NEW] Moving many emails between folders causes Thunderbird to use massive amounts of memory

[Mike Doherty]

Public bug reported:

I tried to move many emails (thousands) from one folder to another. 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.
