First iteration of lusearch slowed down between r15685 and r15688 (biased locking)

Description

See http://jikesrvm.anu.edu.au/cattrack/results/habanero.anu.edu.au/perf/9185/performance_report

This appears to be the only case where we're taking a significant slow down from biased locking. Should investigate to make sure we understand why it's slower and see if there is anything easy to be done to fix the problem.
