nor does the kernel have a python interpreter embedded in it.
I once saw some code which attempted to be compatible with various
versions of gdb and it was not pretty.
here's the commit where they decided to remove all of that and stick
to a single gdb version.
personally I think it's just going to be a pain for those who write
plugins, much more so
than the effort of putting things upstream, we should encourage that,
not lead them into some #ifdef death trap.
