Description:
due to incorrect resource cleanup.
found when running full mtr test-suite in endless loop
(i.e took 72 iterations for crash)

hence can lead to intermittent pb failures

How to repeat:
new testprogram

Suggested fix:
clean up resources

P2 is motivated by mtr/pb relation.
otherwise I would say P3/P4
