Introduce port_yield()
This allows the web workflow send code to yield briefly when
waiting for more room to send in a socket. Waiting for an "interrupt"
could wait forever because the select task only waits for read and
error. Adding wait on write is tricky because much of the time we
don't care if the sockets are ready to write. Using yield avoids
this trickiness.
