I've been using it for quite a while, and pretty much all applications
work fine (although, as you mentioned, some applications hardcode /tmp).
The only problems, I think, that I have come across are when two
programs try to communicate over a named pipe, or shared file, and one
of them hardcodes /tmp, and the other uses $TMP. I don't remember which
programs did that, but I remember it happened at least once.
Another potential problem is if a run a suid (non-root) program that
attempts to create a file in $TMP. But it's suid, so it doesn't run
under my uid, and doesn't have permissions to write to $TMP. But I've
never run across that -- suid programs are pretty uncommon.
