Andy Green d78c93254b cgi: stdout POLLHUP holy grail 
This a) directly discovers cgi stdout POLLUP and b) modulates rx flow control on CGI STDOUT
according to the outgoing writeable service.  When the outgoing writeable service finally sees
0 read() waiting for it even though it was signalled for POLLIN, it knows it is a POLLHUP.

Critically when it sees POLLHUP like that, it leaves the rx flow control defeating any
further stdout POLLIN signalling while the rest of the CGI lifecycle completes, eliminating
busywaiting during the CGI.
