Comment 58 for bug 1255558

A non-technical person managed to cause a system to crash a few minutes after she entered a certain sequence of keystrokes on a terminal that was NOT logged on. The programmer failed to flush the buffer and accepted contamination as well as logon commands. So I have attempted to use her non-technical methods to work around this problem.
