[imp] load balancing / temporary files..

[Liam Hoekenga]

>From what I've read, it sounds like using a SQL based session manager, and
using VFS to store uploaded files are two useful things in trying to
spread the load across a pool of servers.  I'm curious, though, what about
the temp files that aspell (and the other helper apps) create?  I'm most
concerned about aspell... but what if a user gets bounced to a new server
in the middle of spell checking a message?
