That is true, but the test is there to test the fix, which makes it no longer hang. And as these are in the same commit, the test should never hang, unless somebody breaks the fix later. But then hanging could occur with any bug. -- Pieter van Oostrum www: http://pieter.vanoostrum.org/ PGP key: [8DAE142BE17999C4]
