jail vs. nice

A program (a TclX' self-test script) works fine in a normal environment, but 
fails to renice itself, when running in jail (as root):

	==== nice-1.8 nice tests FAILED
	==== Contents of test case:

	    list [nice -1] [nice]

	---- Test generated error; Return code was: 1
	---- Return code should have been one of: 0 2
	---- errorInfo: failed to increment priority: permission denied
	    while executing
	"nice -1"
	    invoked from within
	"list [nice -1] [nice]"
	    ("uplevel" body line 2)
	    invoked from within
	"uplevel 1 $script"

This is new -- just a few months ago the same script was working fine, but it 
is failing now in both 7.0 and 6.2.

Please, advise... Thanks!
