huge memory leaks?

[Christopher Blizzard]

I've started running daily builds again and I've noticed that we've got 
some huge memory leaks, especially when using mail.  After using mail 
for about 20 minutes my memory footprint looks like this:

blizzard 30741  0.0 45.7 109344 57892 pts/0  S    13:11   0:00 
./mozilla-bin -mail

That's 109 meg size, 58 resident.  Is this a known issue?

I thought that outliner was supposed to be a big memory footprint win. :)
