I don't know the answer to the question you asked, but I'd recommend not
using tmpfs for it; just use disk space instead. In this case I *think*
that setting WRKDIRPREFIX is the way to do that, but it might be TMPDIR
instead. 

(modern) Bourne shell syntax:
export WRKDIRPREFIX=/usr/scratch/tmp ;export TMPDIR=/usr/scratch/temp
