In some cases the exception context can be cleared, resulting in None

exception handler, code raises and catches an exception. In both

cases the exception context will be cleared.

To work around this, we save the exception state, run handler code, and

then re-raise the original exception. If another exception occurs, the

saved exception is logged and the new exception is re-raised.

In some cases the caller may not want to re-raise the exception, and

for those circumstances this context provides a reraise flag that

the saved exception will not be logged.

1) A handy function for getting an object down to something that can be

JSON serialized. See to_primitive().

2) Wrappers around loads() and dumps(). The dumps() wrapper will
