They are run when the RTS recognizes that the object is dead, which
is not necessarily at the first GC after the object is unreachable

It is only guaranteed that they are *eventually* run.

See above.

If you are talking about Weak.finalize this would indeed be a bug.
Do you have a small example? Are you using weak pointers and/or
foreign objects?
