#3428: twisted.web.resource.Resource subclasses should not return Deferreds
---------------------+---------------------------

 Keywords:           |  Launchpad Bug:
---------------------+---------------------------
 Twisted Web supports a Deferred return value from neither
 Resource.getChild nor Resource.render.  allmydata/web/ contains a number
 of Resource subclasses which were switched away from Nevow Page - which
 *does* support a Deferred result from these methods.

 The Resource subclasses still work because Nevow's "appserver" is still
 being used but as soon as that is switched to Twisted's "Site" this code
 will all break.

 To make that transition as smooth as possible, change all of this
 application code away from returning Deferred.
