 The FTP server requires code in Twisted that enables asynchronous closing of
-file-upload operations. This code was not in the Twisted-8.2.0 release, and
-has not been committed to SVN trunk as of r27213 (see
-http://twistedmatrix.com/trac/ticket/3462 for details). So it may be
-necessary to apply the following patch. The Tahoe node will refuse to start
-the FTP server if it detects that this patch has not been applied.

+on 23-Feb-2010, slightly too late for the Twisted-10.0 release, but it should
+be present in the next release after that. To use Tahoe's FTP server with

+start the FTP server unless it detects the necessary support code in Twisted.
