Description

BatchlogManagerTest is failing sometimes with the following trace:

    [junit] Testcase: testLegacyReplay(org.apache.cassandra.batchlog.BatchlogManagerTest):      FAILED

Sometimes there are running compactions despite the fact they should have been waited upon before truncate. pause and resume are called on the CompactionStrategyManager appropriately.
