Hi,
I am using web.py for providing a web-interface for an internal
project that uses the gevent library.
Some times on the web-interface, i get the error: gevent is only
usable from a single thread.
Has anyone faced such a problem before? Is there anyway i can overcome
such non-deterministic behavior in the web-interface?
Any insight will be appreciated.
Thanks!
