         This calls the ``find(req)`` method of the `working_set` to see if a
         suitable distribution is already active.  (This may raise
         ``VersionConflict`` if an unsuitable version of the project is already

 For one thing, this makes missing-dependency failures into DistributionNotFound errors instead of ImportErrors, which might be more useful to the user. For another thing, if someone is using distributions that were installed with --multi-version, then they might be not importable until after require_auto_deps() has been run. (The docs claim that this would be the case, but we don't have an example of this happening at this time.)

 * repairer (really the uploader) reads beyond end of input file (Uploadable)
 * new-downloader does not tolerate overreads
 * uploader does lots of tiny reads (inefficient)
 
 This fixes the last two. The uploader still does a single overread at the end
 of the input file, but now that's ok so we can leave it in place. The
 uploader now expects the Uploadable to behave like a normal disk
 file (reading beyond EOF will return less data than was asked for), and now
 the new-downloadable behaves that way.

 This removes the need to use a locally-built (dependency) bin/twistd, and
 removes a big chunk of behavior differences between unix and windows. It
 also happens to resolve the "client node probably started" uncertainty.
