I'd like to have others test this out for a bit: I actually tried the
first "pad to longword" patch you sent out, and it resulted in some
strange NFS behaviour for me (notably it made my mail-connections lock up:
probably because my mail-client is one of the few programs that does a lot
of unaligned writing due to writing out single messages with a fsync() in
between..)
