[Python-Dev] urllib exception compatibility

[Gregory P. Smith]

Is IOError is the right name to use?  OSError is raised for things that are
not IO such as subprocess, dlopen, system.

Nobody likes typing out EnvironmentError and dislike the suggestion of
EMError, should it just be OSError?  errno values are after all OS specific.
