BUG:    Bugs in the bad pixel rejection code were causing the imsurfit task
	to either 1) hang or crash with a segmentation violation or 2)
	display oscillating behavior (sigmas which would decrease then 
	increase again after succesive iterations), if the number of 
	detected bad pixels was very large. The first problem was caused
	by a failure of the code to allocate sufficient space for the bad
	pixel list. The second problem was caused by a failure of the code
	to correctly resolve overlapping regions in some circumstances,
	causing the same pixels to be alternately rejected and included
	in the fit.

STATUS:	Fixed in 2.10.3.
