Yes, I would think so.  The work was done in porting Tcl to
specialized routers where each incoming call would create
another interp to respond.  The Tcl_CloneInterp worked all
down at the C level, even copying bytecodes.

I would think that is the best possible solution, but it isn't
the easiest.  The 8.3 branch that has it was designed to work
in a single-threaded environment.  Other tweaks were made to
save memory (this was for a router, after all), that you would
not want.  Fortunately those should be orthogonal, but making
the whole Tcl_CloneInterp robust for the HEAD would take some
time I imagine (at least a few weeks).
