unittest: Calling tests in liner number order

[Antoon Pardon]

Some time ago I asked whether is would be possible that unittest would
perform the test in order of appearence in the file.

The answers seemed to be negative. Since I really would like this
behaviour I took the trouble of looking throught the source and
I think I found a minor way to get this behaviour.

Now my questions are:

Are other people interrested in this behaviour?
Does the following patch has a chance of being introduced in the
standard python distribution?
