Deprecated since release 2.1.2.
This class will be removed in Python 2.2.
The following derived profiler simulates the old style profiler,
providing errant results on recursive functions. The reason for the
usefulness of this profiler is that it runs faster (i.e., less
overhead) than the old profiler. It still creates all the caller
stats, and is quite useful when there is no recursion in the
user's code. It is also a lot more accurate than the old profiler, as
it does not charge all its overhead time to the user's code.
