I forgot to highlight some things here.

- The -M option is not used anymore. Well actually I just checked and it's
  used by the record perl/python scripts. But it's not needed there anymore, so
  I'll drop it in another pass. But globally it's over with the buffers
  multiplexing needs.

- But I haven't plugged the reordering thing to the live mode, because I'm
  not sure exactly if that would be welcome. With live mode we want the
  events as they arrive, using the reordering there would make it get the
  events per bunches of 2 seconds slices. I guess we'll figure out a solution
  for that.

- Perf lock gets into a better shape. There is still some work to make
  it truly usable though. I need to unearth the event injection thing
  to lower the size of the events, profile by lock classes, etc...

- Various important fixes

Thanks.
