I like the idea!

willu.mailingLists> ( http://en.wikipedia.org/wiki/Color_of_the_bikeshed )

It should be clear by now that the bikeshed must be colored violet
with pink dots.

willu.mailingLists>    Notes:
willu.mailingLists>      - A suspend cert does not stop anyone from
willu.mailingLists> making descendants of the revision, and they'll
willu.mailingLists> appear on lists of heads just as normal. 
willu.mailingLists>      - A suspend cert does stop merge from trying

willu.mailingLists> putting the filter in project_t::get_branch_list(),
willu.mailingLists> project_t::get_branch_heads() and
willu.mailingLists> pick_update_candidates())
willu.mailingLists>      - A suspend cert and update interact in a
willu.mailingLists> somewhat complex manner.  If all update candidates
willu.mailingLists> are suspended then they're all considered.  If
willu.mailingLists> some update candidates are not suspended, then all
willu.mailingLists> the suspended candidates are removed.

willu.mailingLists> Thoughts, comments?

Only one, really: how do we handle irresponsable usage of that cert.
I would normally expect developers to be responsable (and I'm sure
there are a few laughing at this point ;-)), but I can also imagine
cases when developers become childish over issues and could go into a
suspend war.  Should we care?

Cheers,
Richard
