I do. At least RHEL5.6 is going to be around for another year.

I have repeatedly built your patch-series on RHEL5.6 x86_64, which works
fine. But as you pointed out 32bit version fails, other arches possibly too.

My first thought was some kind of lock, so we don't have to care
about each architecture separately.
