      Description

      Create a IRowManager per slave channel, split the memory evenly between them.
      This is to avoid heavy contention inside a single shared row manager by all channels and also (by default) restrict channels to only a percentage of overall memory.

      Future changes will introduce a shared row manager that can use global memory for use by activities like lookup join that wants to use a single large pool shared amongst channels.
