netcdf efficiency

Any plans to "fix" this?  The VMS port has specific information on
how this port could be speeded up (by going to a lower level io via
qio's).  The analogy for unix, I presume, would be to write ones own
level of read/write calls directly.  Obviously I don't expect this to
be done for all platforms, just the ones we run on :-)
