Hello Sreedhar,

Sorry if I wasn't clear enough. What I meant is that I think that it 
would be useful to be able to configure a different completion vector 
mask per process instead of one global completion vector mask for all 
processes that use the rsockets library. Being able to configure one 
completion vector mask per process would make it possible to avoid that 
one busy process negatively impacts the performance of another process 
that uses RDMA.

Bart.
