there is no support for threads in the simulator.  the simulator is
simulating processors, not processes.  so the concept doesn't even
really map.

if/when we finish up multiprocessor support, i'd expect we'd expose
those as threads in gdb.  but that would still be hardware level,
not software level.

it's unclear what you mean, but if you forked the sim, you now have two
sims running ... and if the sim is built into gdb, you now have two gdbs
running ...
