	s/walk-home/scavenge-home/ for consistency with old renamings
	DTC's analysis of the regression test bug is that Python is
		losing a variable because its home CLAMBDA is in one
		COMPONENT while the closing-over CLAMBDA is in another
		COMPONENT, and the one-COMPONENT-at-a-time physical
		environment analysis isn't up to the challenge. Thus
		Python deletes the apparently-unused variable and
		things deteriorate from there. He produced a fix
		involving special-casing top-level variables so that
		physenv analysis never deletes them, but neither he
		nor I was convinced that this covers all the bases.
		So I'll try another approach, making FIND-INITIAL-DFO
		treat the home/closure relationship as just as much
		of a physical dependency as a function call, and so
		prevent separation of the two CLAMBDAs into different
		components. Thus...
