    Description

      As opid is a 32-bit unsigned type internally, but is reported by currentOp as 32-bit signed type, values exceeding 2,147,483,647 are reported as negative numbers. These numbers result in uassert 26823, "invalid op", requiring users to add 2**32 themselves (using the double or NumberLong type) for killing operations. Instead accept negative opids, and do the addition in killOp.
