Makes sense. So instead of having GDB insert watchpoints in all the
threads, we would insert it just in the one we specified in the command.
That could make use of the changes to the watchpoint command, but then
we're discarding Jeff's patches, right?
We would also need to do that cleanup in each thread's debugging
registers due to the kernel cloning the debug registers' values from the
parent process.
