Revert "We do need to send a SIGQUIT to a process/thread, even if it is running"

This reverts commit ef5fffa591e583de26c6ce14f9448104d6dfbe79.

The problem with the commit is that if we SIGQUIT a thread, it
gets exited without updating runtime/etc info. And then we
don't get a new status display on exit.
