OK

> P318 L7: I know you're not changing the current meaning, but that sentence seems to mean that processes must call MPI_FINALIZE if it calls MPI_ABORT. I suspect the idea is that a program that calls MPI_ABORT does not "exit" but rather "aborts," but the way it's written appears contradictory to me. Can we change that to:
> "Unless there has been a call to MPI_ABORT, before each process exits, the process must call MPI_FINALIZE. Each process must ensure that all pending nonblocking communications are (locally) complete before calling MPI_FINALIZE."
A program that calls ABORT does not terminate normally. The requirement to call FINALIZE is only for normal termination.

MPICH currently keeps track most objects (maybe all), but I don't think we should force that on an implementation. I feel users should clean up after themselves; any good programmer already does. Also, this requirement would mean that a buffer allocated with MPI_MEM_ALLOC is freed at MPI_FINALIZE. Do we really want to do that?

NO -- I do not do so. Only objects that where freed by a cal to MPI_xxx_FREE need to be actually deallocated at FINALIZE, if there not so before. The buffer is not allocated by MPI/

Some minor typos in 310-311 are listed below. I don't see ticket 313 (MPI_Init) listed on the agenda currently.
411:47-48: predefined appears twice
418, ln 14 and ln 19: THREAD_INIT -> INIT_THREAD
420:6 than -> then
420:38 rank with -> rank in
420:41 MPI_INFO_ENV needs to be defined somewhere
420:43 ???? still remains
421:9 with be -> will be
421:13 THRAD -> THREAD
421:22 "program. both" -> "program, both"
421:23 what is a cide?
421:24 missing citation
424:17 same' -> same
