buffering writes

[Rob Ross]

Hi James,

This is a very good thing to be thinking about.  Actually though, there 
are no MPI-IO implementations that really do this sort of thing right now, 
and we haven't built this into PnetCDF either.  It's a good idea, and I 
expect to see more implementations (both MPI-IO and high-level libraries 
such as PnetCDF) doing this sort of thing in the future.
