We have experienced failed processing due to shared queue problems and
segfaults under load with the latest two patches from 95 branch on
queries that had run before without problems.
* Allocate thread-local snapshot array statically
* Remember queryId for queries executed using FQS
We did not have time to analyze in detail but reverting patches fixes
the problem (no idea which one could be a culprit..).
Cores are available just in case.
