Comment:

 This is working as intended.  At the time the forked thread is deadlocked,
 the main thread is also deadlocked (the dependency between them is not
 visible to the GC).  If you want to keep the main thread alive manually,
 you can do this:

 {{{
   newStablePtr =<< myThreadId
 }}}

 from the main thread.
