All time -spent in \C{} code (including built-in functions) will be charged to the -Python function that invoked the \C{} code.

There is a fundamental problem with deterministic profilers involving accuracy. The most obvious restriction is that the underlying ``clock'' is only ticking at a rate (typically) of about .001 seconds. Hence no |
