It's fine to start with one ProviderDescriptor here, but there are now two ways you might end up wanting more than one of these:
1) Your program has some threads that are interesting to one provider, and a non-overlapping set that are interesting to another provider.  Since you allow filtering, this is an easy thing to imagine happening.
2) Some might be doing something clever by stacking these filters for the same thread.

We should be prepared to extend this to an ordered list of provider descriptors.  One easy way to get started with this is to only support #1, and use a first match strategy for a given thread.
