Hello?  Where did everybody go...?

[continuing to talk to self...]

Self, first you need to split user name lengths from file name
lengths.  How about FNAMELEN?  Seems reasonable.

NAMELEN = 28
FNAMELEN = 64? 128? 256!?  Hell, might as well fix it now. 256.

In that case the overhead for 9p now gets quite high given all
the Twalks.  So how about a uchar length followed by data?  Makes
sense.

Boy, the fileserver needs a much bigger inode.  I don't see any way
around it.  Of course DIRPERBUF gets a lot smaller.  It's good I
have indexes.

And another thing, there is enough about Plan9 that the user needs
to be aware of, might as well add spaces to file names so the DOS
weenys don't eat your lunch when you do IMAP and CIFS...

Off to work.
