Change 125229 by zec@zec_tca51 on 2007/08/16 19:08:27

	Remove a debugging printf() in VNET_LIST_LOCK() that was
	triggered when acquisition of the exclusive access didn't
	succeed immediately.  Resolving of this condition seems to
	work fine use the condvar signalling from the thread
	releasing the shared lock, hence trim down the debugging
	noise.
