Simon Willnauer commented on LUCENE-5006:
-----------------------------------------
mike since I am going on vacation and I am not very keen to watch our builds
failing with sneaky concurrency problems I created a branch CI build from my
github repo to stress this a bit while I am on vacation...
http://builds.flonkings.com/job/DWPT_Refactoring/ one I come back I can get
this in... I think this makes most sense.

> The concurrency in IW/DW/BD is terrifying: there are many locks involved, not
> just intrinsic locks but IW also has fullFlushLock, commitLock, and there are
> no clear rules about lock order to avoid deadlocks like LUCENE-5002.
> We have to somehow simplify this, and define the allowed concurrent behavior
> eg when an app calls deleteAll while other threads are indexing.
