Please note that this PR also contains the following:

This is because the RunOnThread functionality is necessary for it to function. This PR adds support for reading user_time (the time the CPU has spent executing in user-mode in microseconds) on Linux and Android based systems. Similar support for other systems should be relatively straightforward, but aren't included in this PR.

How about improving libs/prof to add a Sampler implementation for this? We could then expose that to JS, and get the benefit of the other samplers too.

That sounds good. I can add the sampler pretty easily, but wasn't sure where to start with the JS bindings without ending up with a load of duplication?
