[Python-apps-team] Bug#956697: mercurial: flaky autopkgtests

Hi Maintainer

Mercurial's autopkgtests are flaky [1].
I examined the logs of several failed tests and found the following:

Failed test-wireproto-exchangev2-shallow.t: output changed
occurred 8 times

Failed test-narrow-shallow.t: output changed
occurred 3 times

and

Failed test-convert-darcs.t: output changed
Failed test-manifest.t: output changed
Failed test-remotefilelog-prefetch.t: output changed
Failed test-strip.t: output changed
occurred once each.

The tests seem to be more likely to fail on the slower architectures.
In Debian, I see no failures for 5.3.1-1 on amd64, whereas in Ubuntu
there was one failure on amd64, and none on ppc64el.

Please make these tests more reliable or skip them.

Regards
Graham
