/tmp on solaris is usually a 'tmpfs'. A filesystem with no device,
just virtual memory backing it up.

Ie filling up /tmp fills memory, not a disk.

linux just acquired a tmpfs, and it has a 'limit' mount option, to
prevent things like /tmp eating too much memory. solaris doesn't seem
to have a similar option (looking at the sol2.7 man page for tmpfs).

so either live with it, and watch your tmpfs usage, or else put /tmp
on real disk backed storage if you can't afford that kind of risk.
