I know of one Finite Element code base that uses $TMPDIR to write large 
temporary files. These files my exceed 10GB. Thus mounting /tmp as tmpfs 
and having $TMPDIR point to /tmp is not a good solution for this use 
case. Other solutions in this area of HPC probably behave in a similar 
fashion.

Sysadmins for systems that are setup to run this code would have to do 
extra work compared to today's install/setup.

Basically a +1 to the use case Richard described with gcc.
