Compile in support for Low Level TRACE-ing of the main interpreter loop.
When this preprocessor symbol is defined, before PyEval_EvalFrame (eval_frame in
2.3 and 2.2, eval_code2 before that) executes a frame's code it checks the
frame's global namespace for a variable "__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.

Not useful very often, but very useful when needed.
