The NTPNT-specific system PROCEDURE $reinstateMslOsdExcptHandlers resets MAINSAIL's handling of OS exceptions to its default state. This is useful if a call to foreign code has modified the OS exception handlers and set them to a state that does not allow MAINSAIL to catch OS exceptions as it usually does.

$reinstateMslOsdExcptHandlers returns TRUE if and only if it is successful. If a failure occurs, it sets errStr to a STRING describing the error.
