But then won't the eggs be available to all the modpython handlers? I
wanted to have independence between the libraries used by different
modpython handlers. So say I have an application that relies on version
X of a library and another app that uses version Y of the same library.
So each handler has a different PythonPath pointing to a different,
potentially conflicting set of python modules, with some of these served
by python eggs.
