Fix memory leak when using hg commands over http repositories...

Fix memory leak when using hg commands over http repositories When using hg commands over an http repository in a long running process, a httphandler instance is leaked for each command, because of a loop handler.parent -> OpenerDirector and OpenerDirector.handlers -> handler which is not handled by Python's gc. Discussion on #mercurial concluded that removing the __del__ method solved the problem.

      '''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.'''
