> DWPTPool currently uses an indirection called ThreadState to hold DWPT
> instances. This class holds several information that belongs in other places,
> inherits from ReentrantLock and has a mutable nature. Instead we could pool
> the DWPT directly and remove other indirections inside DWPTFlushControl if
> we move some of the ThreadState properties to DWPT directly. The threadpool
> also has a problem that is grows it's ThreadStates to the number of
> concurrently indexing threads but never shrinks it if they are reduced. With
> pooling DWPT directly this limitation could be removed.
> In summary, this component has seen quite some refactoring and requires some
> cleanups and docs changes in order to stay the test of time.
