Vladimir submitted a patch long ago to dynamically recompile bytecode
to add/remove SET_LINENO as needed. I find that approach much more
appealing, because you don't have to pay the SET_LINENO penalty just
because there's some chance you'd want to connect with a debugger. A
long running server process is the prime use case; it benefits from -O
but may need to be debugged.
