and maybe we need to be smart about this;
for me, sharing the backend implementation (the pool part) makes sense,
although a thread pool really is not much code. But a smart thread pool
may be.

as for interfaces, I really really think it's ok to have different
interfaces for usecases that are very different, as long as the
interfaces are logical in their domain. I rather have 2 interfaces, each
logical to their domain, than a forced joined interface that doesn't
really naturally fit either.
