SubProcess: reimplement exec_cmd subclassing Popen and overriding some methods isn't pretty. the code we have was written for py 2.4 or so and the py 2.7 Popen looked quite different. this way with the timer should be less problematic.

MoinMoin Testing Framework
--------------------------

All test modules must be named test_modulename to be included in the
test suite. If you are testing a package, name the test module
test_package_module.

Tests that need the current request, for example to create a page
instance, can refer to self.request. It is injected into all test case
classes by the framework.

Tests that require a certain configuration, like section_numbers = 1, must
use a Config class to define the required configuration within the test class.
