/tmp has the same problem, it's just that the "wasted" resource is disk
space instead of RAM.

So, you would have ... what?  It's not clear to me what you're
proposing here.  It sounds almost as though you're proposing to replace
/tmp and /var/tmp and /usr/tmp with $HOME/tmp or some such.

"/tmp: file system is full" seems pretty clear to me, even to a novice.

No more so than /tmp - or /var/tmp - does already...unless you're
alluding to the prevalence of ramdisks on MSDOS, which isn't what the
context sounded like to me.

Hm, self-tuning, that sounds like (a) a really cool idea and (b) a
maintenance nightmare when it goes wrong.  When will you have a sample
implementation ready for us to experiment with?
