This looks interesting. I'm working on a profiler that is similar, but not
based on timer. Instead, the signal is generated when an hardware
performance counter overflows. It required a special linux kernel module,
and the tracepoint is recorded using LTTng-UST.

This is of course very experimental, requires a special setup, an I don't
even know if it's going to produce good results. I'll report the results in
the coming weeks.

Cheers,
