Behavior of flush when compaction is disabled for a table

Hi,

 When debugging HBASE-16293 <https://issues.apache.org/jira/browse/HBASE-16293> (Ref[1]) , we found that when compaction was disabled for a table. It still waited for blockingWaitTime before 
 forcing a flush (Ref[2]). Can it be changed to flush immediately if compaction is disabled for the table?
 It may block the client as the memstore size exceeds the limit and region server returns RegionTooBusyException.

 Please advice the correct behavior. 

 Thanks,
 Huaxiang Sun
