Hi Jeff,

assuming your concern is in figuring out what constitutes the main 
branch, and what constitutes experimental branches in a project like 
GCC, they have an extensive list of experimental branches (active, 
inactive, etc.) at .

Some of the branches are explicitely marked as not being considered for 
merges into the main branch, for example, while others are there for 
experimental features, backends, frontends, third parties distributing & 
patching gcc, etc. There are different rules for commits to branches, 
for example for release branches, the kind of patches that can go in 
depends on the 'stage' a branch is in, etc.

That may or may not be a suitable model for dealing with experimental 
work for openjdk projects, depending on what the people want & need.

I think this list is a good place for bouncing ideas around. If it needs 
to be more formal / when it needs to be formalized, we can take it to 
gb-discuss and continue the conversation there.
