Correct.  This sounds quite cool;  I attempted something similar entirely
within Valgrind, by implementing a command-line from which you could set
breakpoints, run, etc (see www.cl.cam.ac.uk/~njn25/software.html under
"Interactive Mode").  Problem was that it didn't have all the built-in
infrastructure that gdb provides, particularly converting arbitrary
expressions (eg. foo->bar[5].baz) to addresses.

One feature I've wanted for a while is a way to call tool-specified
functions from GDB, eg. with Memcheck call a function that tells you
whether a particular address is addressable, or if its value is defined.
I tried this with GDB a long time ago, just using the 'call' command, but
had problems with seg faults.  Would this be possible with your patch?
