Subject: [PATCH] Backport of 1.5: Under Jaguar it seems that 'errn' return
 value keyword parameters don't (or don't always?) show up with missed(). I
 think this is a bug in Jaguar, but as it is a potential dangerous problem
 (the OSA event has failed, but the Python code isn't told about this and
 happily continues) this is a quick workaround.
