 I tried the attached patch, and it's appear to be only a half-fix.
 To test it, I made a small server which listens on a named Unix socket
 and a client sending an hello message through it.  Here are the results
 on a 5-CURRENT (about 50 days ago) (`lower' means the program opens the
 socket on the lower filesystem while `upper' means it is on the null
 layer) :
 
 			Without patch		With Dmitry
 						Sivachenko's patch
 
 client(lower) /		OK			OK
 server(lower)
 
 client(upper) /		Failed			OK
 server(lower)
 
 client(lower) /		Failed			Failed
 server(upper)
 
 client(upper) /		OK			OK
 server(upper)
 
 
 I hope this can help.  I tried to understand why it fails, but my
 programming skills are not good enough.
