There is a strong relationship between the FD and the client number (XID).
So, since you can track back to the client connection (Alans' Dtrace 
code) you
should be able to trudge through the connection table and find the 
socket number.
If there is one.  Remember that most clients don't have sockets since 
they are
local to the server.
