Log Message:
-----------
Test the interaction of of tie/untie and hash iterators
This is not intended as a test of *correctness*. This behaviour is
observable by code on CPAN, so potentially some of it will inadvertently be
relying on it (and likely not in any regression test). Hence this "test"
here is intended as a way to alert us if any core code change has the side
effect of alerting this observable behaviour.

Log Message:
-----------
A test for the order of untie/iterator state interaction
This is not intended as a test of *correctness*. The precise ordering of all
the events here is observable by code on CPAN, so potentially some of it
will inadvertently be relying on it (and likely not in any regression test).
Hence this "test" here is intended as a way to alert us if any core code
change has the side effect of altering this observable behaviour, so that we
can document it in the perldelta.

Log Message:
-----------
Free tied hash iterator state immediately at the `untie` call
Previously the state was only freed at the point when the hash was iterated
again, or re-tied, or destroyed.
This shouldn't make any difference to sane code, but the change can be
detected with suitably pathological pure-Perl code, so someone might just
(unwisely) be relying on this undocumented implementation detail.
