I agree, but I am not sure we are any closer to consensus regarding an 
**unambiguous** write with immediate. I am also not totally clear on the 
rules by which we implement new API's. Regardless, it appears that there 
is a strong desire to follow the IB semantics if we go with a standard 
API and if we cannot come to consensus then it should be incorporated as 
an extension.

I would vote for implementing the standard rdma_write_with_ immediate 
API that follows IB semantics.
