It's unlikely that you really want to be using -t malloc, which uses
wired kernel memory that's never released, and can cause kernel panics
if not reserved with the -o option.   -t swap will use
swap-backed memory which is equivalent to an ordinary userland malloc.

However mdconfig has largely been obsoleted by tmpfs which has its own
integrated file-system and so doesn't waste memory on storing deleted
files.
