It certainly doesn't, now; the arguments to 'raise' are just expressions, there is no specialcasing of calling anything. I don't believe it does so with the two-argument raise either -- at least, when experimenting, the body of an exception class's __init__ method is executed before the body of a 'finally' suite.
