The sample labels will not provide instrumenting profiling. What

we cannot currently unwind the C++ stack, including mobile/b2g and
aurora/beta/release (where we don't build with frame pointers), and
should be mostly thought of as a replacement or addition to the
native stack.
We could, however, instrument there.
Do you have an idea on how that would work well with sampling?
