Run logging globally.
The run
function will properly "initialize" and "terminate" the
global Manager.
If the Manager's catchUncaughtException
is True, the run
function will
set an uncaught exception handler that will log all uncaught exceptions,
and set the handler to the original one before run
is complete.
