/Not/ a good idea. Flash memory has a very limited number of writes
available, and would quickly become unusable. It's also /very/ slow
compared to your system memory.

Buy some more memory for your machine, and allocate some RAM disks. You can
use one for swap and another for disk cache, if you want.
