SysFailMgr

The MiscTool call SysFailMgr ($1503) has been modified so that a process calling it is simply killed, instead of causing system operation to stop. This was done because many programs use SysFailMgr when a simple error message would have sufficed. There are, however, some tool and GS/OS errors which are truly system failure messages, and these do cause system operation to stop. These errors are as follows:

$0305	Damaged heartbeat queue detected.
$0308	Damaged heartbeat queue detected.
$0681	Event queue damaged.
$0682	Queue handle damaged.
$08FF	Unclaimed sound interrupt.

What the system does after displaying the message is the same as for a system panic.
