Changing the incoming changeset to patch file by Mercurial Queue?

[Neo Jia]

hi,

I need to maintain an upstream open source project for our group. But
not all of the changes from open source community will be applied
before it is tested by our group internally. So, I think I have two
options here:

1) Converting each incoming changeset to a patch file with "hg
qrefresh" and don't apply them until they are verified.

2) Making branches (but it will become a nightmare once there are two
many upstream changesets are not verified. And it cannot handle the
case that we probably want to skip some open source package if there
is any conflict with our own development.

Any suggestions?

Thanks,
Neo
