Re: [cdt-debug-dev] Add memory monitor dialog

[John Cortell <john.cortell@xxxxxxxxxxxxx>]

Interesting.

gdb doesn't support it, but because anyone can plug in their debugger 
backend to CDT, and because at least some people out there have a 
backend that likes to play "read the users mind", I suppose we'll 
want it supported in the CDT version as well.

Thanks,
John
