Subject: possible bug in dopipe() [walk.c]
Apparently-To: <rc@archone.tamu.edu>

It dopipe, 1 is used as a sentinal to mark fd_pref and fd_out as 
unused. Is it entirely clear that fd 1 will never be used? I would 
think that -1 (_never_ a legal value for a fd) would be a better choice
for the sentinal, or?
