Summary: logging module: default levels do not work as documented.

Initial Comment:
I'm running:

Type "help", "copyright", "credits" or "license" for more 
information.

Under "6.28.2 Handler Objects", it says:

"setLevel(lvl)  Sets the threshold for this handler to lvl. Logging 
messages which are less severe than lvl will be ignored. When a 
handler is created, the level is set to NOTSET (which causes all 
messages to be processed)."

The default level of NOTSET does not work as advertised.  The 
attached program prints:

---------------
ERROR two
DEBUG three
ERROR four
---------------

The first line, "DEBUG one", was not processed.

The level for a handler is different from a level for a logger. 
Filtering first happens at logger level - then at handler level. 
The default level for the root logger is WARNING - hence the 
initial debug message is not printed, but the next one is - 
because you have perviously set the level to DEBUG.
