The module takes a simple approach of any potentiall long running methods off to the gevent hub threadpool for execution.
This lets greenlet code perform parallel queries.
Try the demo script.
$ python demo.py
Populating 'demo.sqlite' ...
gsqlite3: 10 loops, best of 3: 105 msec per loop
sqlite3: 10 loops, best of 3: 243 msec per loop
You can use gsqlite3 with SQLAlchemy by specifying 'sqlite+gsqlite3' as your URL scheme.
