>Description:
	When you renice a proces to 20 and the you renice it to -20
	it wont jump from 20 to -20. it'll jump from 20 to 0
	so you have to renice it again to actually get the -20 value
	*Same thing happens backwards (-20 to 20)
	
>How-To-Repeat:
	"I started from a -20 value"
	
	CASE1:
		-su-2.05b# renice -n 20 -p 426
		426: old priority -20, new priority 0
		-su-2.05b# renice -n 20 -p 426
		426: old priority 0, new priority 20
		-su-2.05b#
	CASE2:
		-su-2.05b# renice -n -20 -p 426
		426: old priority 20, new priority 0
		-su-2.05b# renice -n -20 -p 426
		426: old priority 0, new priority -20
		-su-2.05b#
