The only complaint I've had about walk was the expectation
in the protocol that servers produce the list of Qids all
the way down.  That got in the way when experimenting
with a server that used a hash table of full path names
to speed the walk process.

I remember hearing of some disadvantage to walking directories, but can't remember what it was.  Could someone remind me, please?  Perhaps there was more than one, of course.  Perhaps a performance trick couldn't be employed?

If that's the only issue, I'll be happy.  :)
