Return to 074 CVS log

Up to [Development] / xfs-cmds / xfstests

074 takes ages to complete on my kvm test VM, but scaling it back to the
level used on IRIX makes it complete in slightly under 10 minutes.

I'm not sure if checking for UP vs SMP is the right way to go into slow
mode, but I couldn't think of anything better.
