Is there an MPIRT_Init() and how does it interact with MPI_Init()?
Similarly, for MPI_Initialized() and MPI_Finalize() (and maybe
MPI_Finalized()).
What if channel requests are in use when you try to modify them?
In section 8.3.2, there appear to be umpteen modify calls. Why can't we
just use the regular channel modification call from the previous
section?
Are channel requests equivalent to normal MPI requests in the sense that
you can call the regular MPI_Wait() on one of them? If not, maybe they
should be an entirely different animal.
In 8.7.2, we have a special handle call, I presume, so that we can
specify the request condition. I note that the handler being proposed
in the threads section of the Miscellaneous chapter now has an Info
argument, so could we use the standard MPI-2 handler and pass the
request condition with the info argument?
I note that in the current MPI-2 proposal, only one thread or handler at
a time can be waiting on a request. Do we really need to be different?
