Yes Peter had already asked for this and we have it in plan.
These are listed in the todos I listed corresponding to file based
probes.

- Allowing probes per-executable/per dso.
- Allowing probes across fork.

I have some thoughts on how to achieve these.

However I am not sure which items I should work first
- file based probes or on
- automatically trigger perf uprobes on high overhead functions
that Ingo suggested.

I am not too clear on later so I might as well start thinking on file
based probes.
