If you can kill it, there's a chance GDB will be able to attach to it,
because attaching a debugger to a program delivers a signal to that
program, not unlike what happens when killing it.

Note that I didn't mean "M-x gdb", I meant to invoke GDB from a shell
prompt outside Emacs.  I take it that the rest of your system is not
frozen, only Emacs is.
