I think this needs a bit more work... i.e. I tried it with your script,
event_analyzing_sample and I kinda get meaningful output when pressing
'r' + that script from the top and hists browser.

But with other scripts, and you filtered the -top suffixed ones, that
require special handling, I get things like "Press Control+C to get a
summary", and when I press that, the browser exits, going back to
annotate or report/top browser.

I.e. this only works if we are processing a perf.data file made
specially for that specific script, right? I.e. the record phase is not
integrated at all, just running specific scripts in specific perf.data
files.

How to allow the user to chose appropriate scripts to run each perf.data
file is an aspect of usability that is missing...

Can you ellaborate on the assumptions you made while working on this, do
they match what I described above as how to use this scripts browser?

So I merged part of this patchset, but will wait till more discussion
happens on the browsing part,

Thanks,

- Arnaldo
