Both. As someone pointed out earlier, it is possible to run Thunderbird 
on platforms (FAT file systems, in particular) that don't support large 
files. Beyond that, the issue isn't 32 vs. 64 bit platforms; all of ours 
support large files (except on FAT file systems) even under 32 bit 
environments. However, there are also significant problems within 
Thunderbird itself that prevent large mbox files from working correctly.

No, the problems Kent lists are the minimum that needs to be fixed in 
order to work correctly with large files, even on 64 bit platforms.

I believe it does, yes.
