It really depends what you are going to do. For normal use I would say about 
40MB. I use 50MB here since I occasionally need to do some /tmp heavy stuff 
with CVS. 

The only gotcha with MFS is that once it has allocated memory for the amount of 
space you specify it does not release it back to the system when /tmp usage 
goes down. This means that if you make the MFS too big you can exhaust the 
total memory of the system. I would guess as a safety margin MFS should be no 
bigger than 1/2 of your swap space to allow for VM usage by other programs.
