No it does not. There is currently a SRFI proposition around
threads. I'll wait that it is accepted to implement it in STk, if
Anyway, you can simulate some parallel behaviour with the Tk after
command. Not a real parallel execution but I had made a (not
efficient) preemptive thread system with it a long time ago.

I've a (bad) french version of the first version SICP on my desk, but
cannot find what you are referring to. Can you tell me more precisely
how these are working. Perhaps, it can be simulated with the after
cited before.

Use the -load option. It should work (I'm not able to test since I
have no more Windows on it due to a lack of disk space).
