Main reason for it on Solaris is systems w/ Large core (4GB+) who  (a) never
ever swap or noticably trim proc's and (b) got annoyed at wasiting 10+GB on
Sun's 2xcore rule for swapspace.  If you have  a4GB system w/ 8GB of 
[unused]
swap the odds of filling up /tmp are rather small.  If you have a 128MB 
system
with 10-20MB of swap in use it's a whole lot more likely.

 As always:  YMMV :-)
