There are a number of ways to do this in mercurial. If you've got a set of uncommitted changes, only some of which you want to push out. Just commit the files (or use the record extension to commit only parts of files). Then, update back to the previous revision and commit the remaining changes. This makes 2 heads. You can then update back to the first commit and nudge those changes out ("hg push --rev .", which will only push the current version and any unpushed parent revisions). Switch back to the other revision to finish off your work there and merge the 2 heads together when you're done and ready to push it all. You're basically working with anonymous branches at that point, but if you understand that the commits are really just nodes in a DAG, it's pretty easy to visualize what to do.
