/* LOU: don't do this any more since Layout will do it
* for you once the page starts loading
*
* Here is why we have to do this for now...
*
* | This is important feedback on this new "feature" (or misfeature as
* | it may turn out).
*
* If this is the feature where the front end no longer calls
* XP_InterruptContext() inside fe_GetURL(), but only when data from
* the new URL arrives, then I think I understand what's going on.
*
* | I didn't expect the images that are currently transfering to interfere
* | significantly with the TCP connection setup,
*
* They won't interfere within TCP or IP modules on intervening routers.
* ISDN signalling guarantees perfect scheduling of the D-channel; modem
* link layers are fair.
*
* The problem is this: before, when fe_GetURL() called XP_InterruptContext(),
* the connections for the old document were closed immediately. Those TCP
* closes turned into packets with the FIN flag set on the wire, which went to
* the server over the fairly-scheduled link. The client moved into TCP state
* FIN_WAIT_1, indicating that it had sent a FIN but needed an ACK, and that
* the server had not yet closed its half of the connection. As soon as the
* next TCP segment for this connection arrived at the client, the client TCP
* noticed that the user process had closed, so it aborted the connection by
* sending a RST.
*
* Since the change to the front ends, it appears the old connections don't
* (all) get closed until data on the new connection arrives. The data for
* those old connections that are not yet closed will still be queued in the
* server's TCP, and sent as the client ACKs previous data and updates the
* server's window. There is no way for an HTTP daemon to cancel the write
* or send syscalls that enqueued this data, once the syscall has returned.
* Only a RST from the client for each old connection will cause the server
* to kill its enqueued data.
*
* I doubt there is much data in the fairly narrow pipe between server and
* client. Because the pipe is narrow, the server TCP has not opened its
* congestion window, and there cannot be much data in flight. The problem
* is lack of abort because of lack of close() when the new URL is clicked.
*
* | Perhaps there is some TCP magic that we can do
* | to cause the new stream to have absolute priority over other TCP
* | streams.
*
* No such magic, nor any need for it in this scenario.
*
* | I could also pause all the transfering connections while
* | we are waiting.
*
* Only a close, which guarantees an abort when more old data arrives, will
* do the trick. Anything else requires server mods as well as client.
