Shouldn't require downtime if you do a quick:

	mv /tmp /tmp-old ; mkdir --mode=1777 /tmp 

Plus maybe moving the file from /tmp-old/ to /tmp/... and /tmp-old can be 
deleted as soon as no processes accessing it. Check with fuser/lsof.

Yep, I like keeping /tmp on tmpfs, which is what it says it is...
