Michael McCandless commented on LUCENE-2783:
--------------------------------------------

OK, thanks for bringing closure!  Note that the autoCommit=true is deprecated, and as of 3.0
IW is always autoCommit=false.

> If autoCommit == true a merge usually triggers a commit. A commit (prepareCommit) can
trigger a merge vi the flush method. There is a synchronization mechanism for commit (commitLock)
and a separate synchronization mechanism for merging (ConcurrentMergeScheduler.wait). If one
thread holds the commitLock monitor and another one holds the ConcurrentMergeScheduler monitor
we have a deadlock.
