temp path for spamassassin

[Lindsay Snider]

I wanted to try and have SpamAssassin use /dev/shm for its temporary files 
that it creates for DCC and Razor.  From checking out SA's source, it seems 
to only look for an env $TMP or $TMPDIR.  Anyone know of a clever way to set 
environmental variables in MS or perhaps trick SA in to using /dev/shm.  man 
Mail::SpamAssassin::Conf has a path variable for just about everything but 
not its tmp path.
