New description:

 {{{
 This is re my posting under the subject "Weak pointers,
 garbage collection & deadlocks" on
 glasgow-haskell-users.

 Basically, the problem is that finaliser threads that
 the next GC would generate aren't taken into account
 when determining whether there are any more threads to
 run.

 I attach a program reproducing the error.
