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.
#!/bin/sh
hg init a
cd a
hg init b
echo x > b/x
echo '# should print nothing'
hg add b
hg st
echo '# should fail'
hg st b/x
hg add b/x
echo '# should fail'
hg add b b/x
hg st
echo '# should arguably print nothing'
hg st b
echo a > a
hg ci -Ama a
echo '# should fail'
hg mv a b
