It could be split but, currently, the other debuggers couldn't use these other
windows. To run the relevant commands (stack, locals, breakpoint list) behind
the users back places requirements on the syntax of the debugger output.  I've
approached the Python developers about this but met with limited interest.
With Java, I think different debuggers generate different output. Without a
formally defined interface, parsing the output is a precarious approach that
is likely to break. Hopefully, I can help GDB's interface evolve but I have no
input to the other debuggers.
