Alexander,

your library is really interesting, I didn't know it. I'd appreciate
if you could think about how to integrate coev with the "green"
psycopg branch.

Other libraries have a Python roundtrip every time a libpq call
blocks. It seems your library wouldn't need that, but currently I am
only expecting a Python callback to register the wait function.

If you have an idea about how to allow a C callback to be registered
in psycopg, your library could benefit of the whole nonblocking I/O
support and still avoid the Python overhead. This, and any other
comments, are welcome.
