Eugene,
It appears this is a sm BTL problem. The prepare_src function can be
called with any size. The BTL should check the size against the eager
and return a descriptor that match the size requested.

(Rich: same question as I asked you in private e-mail.)
Should the first fragment of a message be an eager fragment even when
the message is long and a rendezvous protocol is employed?
So
far as I can tell, a long MPI_Send starts like this:
MPI_Send()
mca_pml_ob1_send()
mca_pml_o

Ah! Sorry; I thought we had some discussion about that but perhaps it

I'll agree with that if we know for sure that free(NULL) is
universally supported. You mentioned "a few man pages" -- how
universal is this support?
Per the call today, I ran the reduce-hang.c test on a single x86 4-
core xeon node with both 1.2.8 and 1.2.9. I see the same behavior
with both:
- none of the processes hang; they all keep iterating over MPI_REDUCE
- the iteration numbers sent to stdout are more-or-less in sync
- memory usage

Let's say someone makes changes to the trunk. I guess I bring those

I guess that if the free function supports the NULL pointer we should
