Anyone happen to know which tool it is? I remember we had had issues
with FC3 around this area, but I thought we resolved them, so it's
supprising to me that FC6 has issues.

Yeah, that's what prompted this removal. After the s390 guys said that
they were all good to go, I figured no one else would have problems with
If it turns out there still are issues with older userspaces like FC6

will have to fix up the regression.
