CHECK_FOR_INTERRUPTS() would reset the event wait state. Hm.. You may be right about the WARNING and it would be better to not rely on that. Do you remember the states which may be triggered? > OK, so I attached the updated version of the patch. > Thanks for the review! Actually, I have some questions: 1) Should a new wait event be added in recoveryPausesHere()? That would be IMO useful. 2) Perhaps those two points should be replaced with WaitLatch(), where we would use the new wait events introduced? -- Michael
