This patch takes care of a problem with the stopping code.
The function inside the while condition returns 0 to signify a problem.
A problem could be for example a bad command or a bad version of the
mconsole client.
A bad command would terminate the stopping loop and resume the kernel.
This is a problem.
A better solution is to make the loop infinite and don't leave it
until we are explicitly told to.
