How about --short_socket_write and both --short_socket_read and
--short_socket_write.

Comment added - TODO below explains why these don't work yet.

I still don't see a pkcert directory in this changelist.

Added.

Remove the print. Not sure it is usefully to get google.dk html printed when you
run the test.

[Bill Hesse, 2012/11/13 20:11:08]

Done.
