Subject: Remove unneeded lock in nogc lazy list find_at_.
X-Git-Tag: v2.1.0~298^2
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=2adb421951b367335c52d096d98ea8eb4f96214d;p=libcds.git

Remove unneeded lock in nogc lazy list find_at_.

Call to a comparator doesn't require the lock, so the lock in
find_at_ method is odd, so this patch removes that lock.
