I think explicit lock is redundant, synchronized method can be used.

Lets introduce getter for extWait (perhaps for HeavyQueriesTracker.qrys.keySet() too)

Test still can be flaky in some cases, even with EXT_WAIT_REL_ERR. Root cause to this error is async updating of
U.currentTimeMillis(). Instead I propose to modify sleep a little bit, we can replace Thread.sleep(EXT_WAIT_TIME); to something like:
long sleepStartTs = U.currentTimeMillis();
while (U.currentTimeMillis() - sleepStartTs <= EXT_WAIT_REL_ERR)
doSleep(100L);
And in this case we can check extWait without EXT_WAIT_REL_ERR
