Good idea.

We did not put this in, although it should be quite easy to add it.
So far in the eclipse debug framework/UI there was no need for it.

But if you can come up with a clean Interface(set of methods) of
what you need we could work things and put it in the CDI and implement
it in the GDB/MI plugin.  The annoying thing is that GDB/MI does not
have any "mi" command for this, so we will have to send "cli" command
and do weird parsing on the output.
