this allows a return without checking syncobj, avoiding overhead,
but when a query still isn't completing after multiple checks then
try checking the pool directly
this circumvents the usual qbo mechanism in specific cases (e.g., Everspace)
where an app fires off a million timestamp queries and the overhead of
checking a timeline semaphore kills perf
