I totally agree. When doing the `info core' patch, I often found myself
thinking about how `info proc mappings' needed to be reworked.

Anyway, just to be clear, will this new command be implemented
differently than the current `info proc mappings'? I don't know about
you, but cat'ing /proc/PID/maps is something that could be improved.

Thanks.
