Hi,

Here are a few perf patches that (hopefully) fix a number of reported
(and at least one unreported afaik) issues as triggered by Vince's
fuzzer.

After a few days of staring at that event->ctx mess and writing
increasingly horrible patches, I came up with the approach from patch 3.
It still isn't pretty or straight forward though; please give it careful
consideration.

Jiri reported some success on an slightly older stack.
