If Smoke hangs but you can still
interact with the operating system, you must use either the kill
alias defined in the Smoke .cshrc file
or the command
in conjunction with the individual process IDs.
WarningThese kill procedures
should not be used to exit Smoke unless the application is
hung or otherwise not responding. Killing processes indiscriminately
can cause system problems. Under normal conditions, you should use
one of the exit procedures described in
Exiting Smoke.
