Wait a minute, that's wrong. TCP/IP guarantees delivery. A write to
socket won't return until the data is acknowledged by the client. PHP
does buffering too, but it's flushed prior to the session closing. And
a database connection would only be destroyed at the very end of the
request handling process. So if you don't close it explicitly, it won't
be released until the page is fully transferred.
