No need to apologize - you raised valid questions that have come up in the past and i am pretty good at ignoring early-in-the-morning aspect of mails ;-)

Great! :-)
If someone wants to dust off the 'trace' utility patches that are still in tip:tmp.perf/trace that would be fantastic. Thomas and Peter prototyped an ftrace-esque buffering model there, to have all events associated with a single fd (and hence a single [per cpu] buffer).
Warning, they conflict left and right with the current code:
kernel/sched.c kernel/trace/trace.c tools/perf/Makefile tools/perf/builtin-record.c tools/perf/util/event.c tools/perf/util/header.c tools/perf/util/parse-events.c tools/perf/util/session.c tools/perf/util/session.h
So it's quite a bit of work - and of course it was all very unfinished, not even reaching prototype stage really.
Thanks,
Ingo
