Incompatible with pytest-cov

[jayvdb]

As this plugin and coverage use sys.settrace, they are incompatible.

It would be lovely if there was a way to share the coverage data. Perhaps pytest-cov exposes it in a way that this plugin could use it?

Might be able to get cov data like

I think that's going to be tricky, if not impossible. The main problem is that tracer is very minimal with what it traces, but very fast - much faster than coverage. Its call graph is also drastically simpler and optimized for quick lookups for the kind of stuff fastest needs.

Note that I'm 100% behind the idea of using coverage's data, but realistically I doubt if I'll be the one who implements it.
