Al has been away for a bit, and I prepared the last VFS pull.  I'll pick
it up for now and either Al or I will send it on before next weekend.

Can I get a tested-by tag from you for the patch?  Can anyone else
please cross check it?  The new total value might be different from
the old size value when we do a short write, but I can't see how
an async write would be a good thing if we had to finish the remainder
using buffered I/O if the old code really allowed that.
