Pete,

We have a winner.

When I change the unex size to 8 or 16 KB, it succeeds. When I switch  
it back to 4 KB, it fails.

The code should check that bmi_max_unexp_payload > small_io_size  
before returning.

I will also increase the unex size in bmi_mx to 8 KB to avoid having  
to modify PVFS2.
