You could create a RAM disk to hold your intermediate files,
something along the lines of:
Ramdir="/dev/shm/${FUNCNAME[0]}$(printf '%(%s)T' -1)"
$ mkdir -p "$Ramdir"
The first line (which I run in a bash function, for a quite different
purpose) creates a pseudounique but recognizable name, and the second
line creates the directory.
