[CF] WaitForFlush() instead of sleeping

Browse Source 
Summary: If we sleep for 300ms the test fails in valgrind because it takes more than 300ms to flush. This way we WaitForFlush() when we're expecting flush, but still sleep and check if the flush happens even though it's not supposed to.

Test Plan: notest
