Any thoughts as to how one could allow N userspace agents to log to a

main reasons we maintain separate logs in Android today, and are
likely to continue doing so until we figure out how resolve the issue.
note that you still don't prevent one app from blowing out the logs, all
you do is separate the logs into a handfulof categories and limit the app
(through standard filesystem permissions) to only blowing out one category
of logs.
or do I misunderstand this and you actually keep a separate queue for each
pid (which would seem to be a problem as you no longer know how much space
you need)
