That last argument to proxy_check_input()?  It's the timeout.   
Setting it to 0 means "don't time out".  I'm sure the theory is that  
the underlying select() will return when the backend's poptimeout  
happens, and the connection is closed.  It would be good to know why  
that's not happening as expected.  Of course, the fact that bitpipe()  
isn't checking the return value of prot_flush() is also bug.
