Easiest thing might be to use /dev/shm. I used it during
development to store intermediate data that was later to be
transfered via a fifo...
Basically check for existence of "/dev/shm" (exists on my cygwin).
if "tmp" didn't already exist, create it w/options similar to
/tmp (only owner can delete/edit):
mkdir -m 1777 /tmp/shm/tmp
**Warning, "writes" to /dev/shm/tmp (or /dev/mem) can fill up
your system's memory, so its only good for "small files"
(small being well under your system's free memory amount).
