New submission from Bob Alexander:

Attempting to use os.path.exists on a Windows drive that is a mobile device 
mount point with nothing mounted pops up a dialog asking to insert a device. 
This makes it impossible to search a set of drives for a specific file without 
the possibility of unnecessary user interaction -- for example looking for the 
drive that has a specific flash drive inserted.

This behavior is likely related to bug 9035 regarding "os.path.ismount" 
behavior on Windows.

The more correct behavior (IMO) would be to quietly return exists=False for 
drives with nothing mounted. In fact, I tried the same operation with Java and 
Ruby programs, and both simply return false with no popup.
