Correct.  This is longstanding behavior.  Stop signals are ignored if
there is no parent process.  Apparently, the theory is that since
SIGSTOP is a UNIX thing, it makes no sense to stop a process if no other
process is around to recognize that fact.  This prevents a user from
typing CTRL-Z and creating a suspended process which requires restarting
from another window.
