If I understand correctly your question, then we don't need any
extension. Each request has a unique ID (from PERUSE perspective).
However, if I remember well this is only half implemented in our
PERUSE layer (i.e. it works only for expected requests). This should
be quite easy to fix, if someone invest few hours into it.

For the context id, a user can always use the c2f function to get the
fortran ID (which for Open MPI is the communicator ID).
