Occasionally a file("http://foobar.com") will timeout.
Subsequenetly an open socket to foobar.com in CLOSE_WAIT may persist.

it the same bug:
http://bugs.php.net/bug.php?id=17964

when a connection is not closed from server side (e.g. timeout, but it can be a ftp (without "bye") or other protocols closed with fclose and not by server itself)
it leads to a CLOSE_WAIT state (for indefinite time on server side!!!).

CLOSE_WAIT is appropriate.

It is appropriate for PHP to not clean up after itself and
waste kernel resources? PHP should close the socket itself
once the socket is put in a CLOSE_WAIT state, such as when
a timeout occurs.
