I assume this would mean use "interp create".  It's even on dejagnu's TODO file:

  * Use a throw-away slave interpreter for running each test case.

I think the trouble would be globals that _are_ supposed to be persistent
across tests, like e.g., "portnum", or whatever other globals board
files can come up with.  We'd need some common way to make
those "master interp" owned variables (through aliases or env vars?).
Alternatively, we could save/restore globals, but there's no globals
standard naming scheme in place to make that remotely sane.
