17301	Keep the connection open when doing upgrades or long-running operations	markjaquith		"When we do long-running operations like upgrades-over-FTP, we may go a while without sending any data, which may cause the connection to be closed. We should investigate whether we can send some ""hey, still here"" dummy data down the pipe to keep the connection from being unceremoniously closed on us.

For example, Rackspace Cloud Sites runs behind load balancers that cut the connection after 30 seconds of no data. I was able to defeat it by manually flushing some dummy data like so:

{{{
<?php

for ( $i = 1; $i < 46; $i++ ) {
	echo ""$i...<br />\r\n"";
	flush();
	sleep( 1 );
}
echo ""DONE"";
}}}"	enhancement	new	normal	Awaiting Review	General		normal
