(confusing enough?  who names their work machine 'home'?)

Of course, my work domain is so big that 'echo //hom*' takes minutes, due to 
the large number of known hosts that are not currently accessible, so I can't 
easily test whether //home is a known host using readdir.  But it seems like 
this problem could be recreated on a much smaller network, by just 
disconnecting an appropriate machine from the network (although I won't be able 
to try that until I'm back home).  It still seems like chdir() should do some 
sort of stat() test rather than just a successful SMB name resolution when 
attempting to change to //name.
