*Attach an NMI handler at runtime*

Type: ``bool``

Help
====

The kernel provides a simple NMI handler that simply hangs in a tight
loop if triggered. This fills the requirement that there must be an
NMI handler installed when the CPU boots. If a custom handler is
needed, enable this option and attach it via _NmiHandlerSet().
