Deprecated since release 2.1.2.
This class will be removed in Python 2.2.
This profiler is the fastest derived profile example. It does not
calculate caller-callee relationships, and does not calculate
cumulative time under a function. It only calculates time spent in a
function, so it runs very quickly (re: very low overhead). In truth,
the basic profiler is so fast, that is probably not worth the savings
to give up the data, but this class still provides a nice example.
