HotSpot workflow

[Andrew Haley]

I'm having some practical problems with the HotSpot workflow.

I usually have several patches on the fly at any time, but webrev and
Mercurial don't really help.  "hg push" and "hg merge" work on the
whole repo, not just a changeset, so I've been manually saving
changesets and re-merging them into the master tree, which is very
error-prone and has led to some mistakes submitting changes.

Also, the need to submit a change as a single changeset makes it
awkward to commit regularly as I work on a patch; I can't find any way
to merge a set of changes into a single changeset and push that.

So, what do you do?  Do you keep a source tree checked out for every
webrev?  Do you regularly commit as you work?  Am I missing
some tricks?

Thanks,
Andrew.
