Err, looks like testOverlappingIndexPatterns times out and has lots of waiting threads. Then, later, testExtractFields complains about a negative breaker o.O

@dnhatn , do you have any idea what could be up here? @idegtiarenko , I recall we were fixing what thread pool we were running esql on, could that be in any way related, maybe?

Fixed by #131370 or #130963.
