I realize this but... I figured waiting a few extra ticks of time before 
timing
out was probably a good thing with respect to soft mounts to slow 
servers...
Especially  since EIO errors can be pretty disruptive...

And as I see, its a no-op with a fast (or slow) client  talking to a fast
server because the timeout will should never happen... (i.e. the waiting
thread will get the response before the time out occurs)....
