+1. But should we _exit(2) only in critical section or always in case of 
postmaster death?

Another question that was bothering Kirill is do we want a test that naturally 
reproduces WaitEventSetWaitBlock() under critical section so that we can 
observe a corruption? Or is it kind of obvious from code that such things might 
happen?
Existing test is adding WaitEventSetWaitBlock() via injection point to a place 
where it was not present before. Though with existing test at hand we can check 
that fix is curing WaitEventSetWaitBlock() against critical section.
