Thanks for tracking that down. Komodo's variable viewer (in the Debug 
Output tab) was trying to get information about the "server" object's 
attributes. "server" is an xmlrpclib.ServerProxy object. Because of 
xmlrpclib.ServerProxy's __getattr__ -- which returns a remote method 
callable for each call -- Komodo was unnecessarily resulting in calls to 
the server. This will be fixed in the next release so that no remote 
calls are made on the "server" object unless the you specifically 
request this in the variable view by opening the "server" items tree 
view in the "Locals" or "Globals" tabs.

Cheers,
Trent
