Thanks. I was aware of the Expanding_*_client classes but I was mistaken
in the belief that the thread creation used rm in some implicit way
instead of going through that session. My mistake.
I'll write and submit the following patches:
1) expand Expanding_rm_session_client to handle the necessary functions
2) create Expanding_cpu_session_client and the assorted fixes (I have
this code already and just need to polish it).
ps. Thanks for the patience to help with this.
