From: Vladimir Sementsov-Ogievskiy <address@hidden>
Though it is not intended to be reached through normal circumstances,
if we do not gracefully deconstruct the transaction QLIST, we may wind
up with stale pointers in the list.
The rest of this series attempts to address the underlying issues,
but this should fix list inconsistencies.
