grep for kdb?

[linas@xxxxxxxxxxxxxx]

I've got a request for a 'trivial' kdb feature: something 'grep'-like
for searching system memory.

I've got some corrupted system memory and I can't tell who did it, so
I'd like to be able to search all of system memory and see if I can find
anything pointing at it.  Hopefully, If I can see who is pointing at
my corrupt ram, I'd have a good idea of where to look for a bug. 
Right now, it feels more like snark-hunting.

Comments? Suggestions?
