Yes, the garbage collector will (well, certainly should) find and kill such threads. By "kill" I mean that they get sent an asynchronous exception of some kind (I hope the documentation says which) so that the thread has a chance to clean up rather than being forcibly terminated. I'm not quite sure where this fact should be documented -- documentation for GHC itself, or for the STM library? -- but it surely should be somewhere.
