>Description:

	/etc/daily can hang under some circumstances.  (Such as 
	"df" hanging when the server for an imported nfs-filesystem is
	offline.)

	When the stuck nfs server is brought back online all the
	wedged /etc/daily's race it out and trip all over each other.

>How-To-Repeat:
	
	mount some-rarely-used-server:/mnt
	shutdown  some-rarely-used-server
	wait 2 days.
	power up some-rarely-used-server
	watch the fun begin.
