	abstract = {It has become a commonplace that triangular systems are solved tohigher accuracy than their condition would warrant. This observation is
not true in general, and counterexamples are easy to construct. However,
it is often true of the triangular matrices from pivoted LU or QR
decompositions. It is shown that this fact is closely connected with the
rank-revealing character of these decompositions.
