At the sprint, we discussed a plan for a related concept called 'liquid
hg' that would allow marking a set of changesets and their ancestors
'frozen' (permanent, can't be modified) and another set of changesets
and their descendants 'dead' (won't be propagated, may be
garbage-collected). This information would be propagated on push/pull
with the pushkeys mechanism we introduced in 1.5.

Changesets in between these two ranges would be 'liquid', meaning open
for modification with tools like MQ and rebase.
