I didn't catch your drift there until I found out why there are no
really fast RAM drives. The fastest drive is no drive at all, and
that is possible by writing the simulation data to a temp file.
Windows has a special attribute for that ( _O_SHORT_LIVED ) and
Linux has shm.
This means that there is no need for iSPICE to require a fast disk
as long as there is enough free memory. And nice: I didn't have to
change the code much, only the file attributes for one CREATE-FILE.
With this change there is a slight possibility of losing data
when the OS crashes before the RAM runs out, or before there's
a reboot.
