That way, I can set ‘sys.dont_write_bytecode’ to the value I need in

Have I re-invented a context manager which already exists? Is there a
better way to do what ‘preserve_value’ is doing?
Depends on the context (ho ho..), but if it's testing, then have a look at:
http://packages.python.org/testfixtures/mocking.html#the-context-manager
There's plenty of other goodies you may like in there too...
cheers,
Chris
