When this preprocessor symbol is defined, before PyEval_EvalFrame executes a
frame's code it checks the frame's global namespace for a variable
"__ltrace__". If such a variable is found, mounds of information about what
"__lltrace__". If such a variable is found, mounds of information about what
the interpreter is doing are sprayed to stdout, such as every opcode and opcode
argument and values pushed onto and popped off the value stack.
