http://codespeed.dak8s.net:8000/timeline/#/?exe=1,3&ben=mapRemove.HEAP&env=2&revs=200&equid=off&quarts=on&extr=on


All affected benchmarks:
listAdd.HEAP
listAppend.HEAP
listGet.HEAP
listGetAndIterate.HEAP
listUpdate.HEAP
mapAdd.HEAP
mapIsEmpty.HEAP
mapKeys.HEAP
mapRemove.HEAP
mapUpdate.HEAP
mapValues.HEAP
valueAdd.HEAP

good commit: b3b50559cf22f188ddb9cad62ecfb83881c47961
bad commit: fc4f255644a64bb556b0dcefb165a9c772164c5b

It's very likely fc4f255644a64bb556b0dcefb165a9c772164c5b is the cause of the regression (in between there are only docs updates and this one is heap-related).
