svn subrepos: work around checkout obstructions (issue2752)...

svn subrepos: work around checkout obstructions (issue2752) We do this by ensuring the working copy is clean and then blowing away the working copy and replacing it with one from the desired path. We could probably use 'svn switch' to do this more efficiently, but there's some subtle logic required to get that right and this is more likely to work reliably.

      '''Low-level interface to the Linux inotify subsystem.

      The inotify subsystem provides an efficient mechanism for file status

      monitoring and change notification.

      This package provides the low-level inotify system call interface and

      associated constants and helper functions.

      For a higher-level interface that remains highly efficient, use the

      inotify.watcher package.'''
