Change 106541 by rdivacky at rdivacky_witten on 2006/09/23 09:38:17

	This fixes clone05 test from LTP. But I dont understand the logic much this will
	need someone to look at it because its possible that we are waiting and timeouting
	or something. Anyway - linux_vfork() doesnt seem to need this which is strange.
