> Currently, the MergeContent processor creates a separate ProcessSession for 
> each FlowFile that it pulls. This is done so that we can ensure that we can 
> commit all Process Sessions when a bin is full. Unfortunately, this means 
> that MergeContent is required to call ProcessSession.get() many times, which 
> adds a lot of contention on the FlowFile Queue. If we allow FlowFiles to be 
> migrated from 1 session to another, we can have a session per bin, and then 
> use ProcessSession.get(100) to greatly reduce lock contention. This will 
> likely have benefits in other processors as well.
