I don't know about Tkinter, but Twisted can be run in a thread other than
the main thread.  Several projects make use of this feature extensively, so
while I wouldn't recommend it, it should certainly work.

Perhaps you did something wrong in setting it up, or perhaps you have found
a bug.  Can you post a minimal example to reproduce this to Twisted's bug
tracker?
