Change 111927 by imp at imp_lighthouse on 2006/12/19 07:39:51

	Unwisely touch this file: add debugging code to gather more data on
	a condition I see far too often.  I fear I'll have to implement COR
	reset to properly fix this.  Basically, the firmware goes out to
	lunch, we set 'gone' but then bad things happen from there...
