yum delay processing exclude list

[Jay Cliburn <jacliburn bellsouth net>]

I have an x86_64 rawhide machine that's configured to exclude all i?86
packages from updates, and lately it takes a *very* long time to go
through the global exclude list during a yum update.  If I remove
"exclude=*i?86" from yum.conf, the update proceeds at the speed to which
I'm accustomed.

With "exclude=*.i?86" in yum.conf, an (empty) update takes up to a
minute and a half, and pegs both my cpus.  Without "exclude=*i?86," the
same update takes less than 3 seconds.

With extras-development enabled, processing the global exclude list
takes over 5 minutes.

Is this a bug, or expected behavior with rawhide yum (3.1.3-2.fc7)?
