Any chance that pdb can utilize similar technique? Or this > doesn't make sense for pdb? > I guess it's possible. It probably depends on how you're using the debugger. It sounds like PyCharm is injecting bytecode for specified breakpoints and so I suspect the speed is only there when you press "debug" and are not stepping through line-by-line. Getting gdb to have the same level of sophistication might not be too bad as long as you keep the hook simple and you're okay injected new bytecode just before a frame begins execution.
