It should be a good reference, it's gotten a lot of testing.

I think we can both be right. The select.poll() code does not really
map to the low level poll() call. In fact, it maps much better to the
epoll() call. It appears that your new API is really a superset of the
the select.poll() interface. The only thing which keeps a user from
just importing your module and using it with code which uses the
existing interface is that you've changed names. Why not change the
names so that it Just Works?

Also, everything but the edge-triggered functionality could be
incorporated back into the select.poll() interface (where "everything"
means the modify() call.)
