Could be relevant: we encountered BlockingIOError when using ipython with uvloop. Also saw likewise report here https://github.com/ipython/ipython/issues/12563

Also note that, the initialization of custom CSR's may require access to the processor instance (i.e. to inspect a relevant feature / state of the processor). This is why there...

If an extension introduces custom CSR's to the processor, isn't it by definition modifying (extending) the processor's state? The bright side of `extension_t::reset()` is that its name explicitly suggests that...

@arrv-sc thank you! The updated extension api looks good to me.
