In Python 2.4 the interpreter/profile module were changed to allow profiling of C function calls: http://svn.python.org/view?view=rev&revision=35570 We don't do this. We'd have to add hooks into probably PyBuiltin{Function,Method}Narrow, like the trace/profile hooks in PyTableCode. That might affect performance because we'd need to look at the ThreadState everytime to see if tracing was enabled This is low priority since we have better profiling tools on the JVM. test_profile's output has been tweaked to reflect the lack of this feature. We might never support this, in that case we'll just keep this open until we clearly document that fact (we really need to revive that old CPython vs Jython differences doc).
