Goal

tmshutdown -w/-k may be used to speed up the shutdown process. Most of the time
a SIGTERM is sent by tmshutdown -w but depending on the delay specified a SIGKILL
may be issued. The SIGTERM signal is trappable is the Tuxedo libraries contain 
a corresponding signal handler to force a process receiving the SIGTERM signal to
terminate properly. As opposed to SIGTERM, SIGKILL is not trappable and may
cause the process to terminate is any portion of code, even critical one. Thus sending
a SIGKILL may cause the process to terminate while updating the BB with potential
damage to the BB structure.
