Oh thanks for the clarification. I always wondered why a computer
would need a tap.

And it does not matter at all whether systemtap can use this or
not. If the main debuggers used like gdb are not going to use it then
it's a complete waste. We don't need another debugging interface just
for a single esoteric use case.

Thanks,
