distinguish between these two states:
. just issued connect(), polling for writability to find out when connect()
completed
. already connected, waiting for data from the server so polling for
readability
by only polling for writability during the first state, we avoid some
logic in test() which inappropriately writes multiple requests to the
server
btw, the most basic SSL test segfaulted before and after this commit
