Hello, I've almost completed everything I want to do for the release of psycopg 2.8. However I found some dodgy management of the cursor state while not holding the GIL: this could be the cause of errors such as double free (#384) and "no result to fetch" on select (#346) in multithread environments.
As I don't have a reproducible failing case the best way to verify the fixes is to provide a package to the people who have reported the problems. Cheers -- Daniele
