Regarding cancelling generalized requests, 137/45 should say, as in
MPI-1, that MPI marks the request as "cancelled" not "complete". The
user is still required to call MPI_Test/MPI_Wait. Also, after a call to
MPI_Cancel, the request either completes entirely or no part of it
gets completed, but nothing in between. The statement in parenthesis on
line 47 is a bit misleading.
Few minor typos:
132/36: should be meta_req
132/37: always
132/42: instantiation
136/32: MPI_GR_MARK_COMPLETE
148/19: array_errorcodes, count
148/1 and 148/6: \consti{MPI\_ERR\_LASTCODE}
