It would be convenient if it were possible to divide one
datetime.timedelta object by another to determine their relative durations.

Were the datetime module pure Python a crude solution would just be to
add two methods like this:

	def toMicroseconds(self):
		return ((self.days * 24 * 60) + self.seconds * 1000000) +
self.microseconds
	
	def __truediv__(self, other):
		return self.toMicroseconds() / other.toMicroseconds()

However, I don't understand know the Python C API well enough to know
how to patch the C module.
