Change 14877 by rwatson at rwatson_curry on 2002/07/24 19:21:02

	Hopefully a bug fix for a bug whereby when one pipe end is
	terminated, the label is prematurely destroyed, resulting in
	a blank label during follow-up policy checks.  I believe this
	change modifies the logic so that the pipe label is destroyed
	only when the second end-point is removed.  We'll see if this
	corrects the problem I'm bumping into.
