[Yum] yum 2.4.3 dual-arch dependency problem

I have this installed on my x86_64 system with yum 2.4.3:


a.x86_64 requires the newest version of b.x86_64.

When an update becomes available for a.x86_64, I do a "yum update a".  
The new "a" requires the new b.x86_64.  Fine, no problems... the 
packages are in a sane distribution where the new b is provided.  So yum 
solves the dependency by preparing to upgrade b.x86_64 too.

However, the transaction fails, because b.i386 isn't getting upgraded... 
and b.i386 old isn't same version as b.x86_64 new and they conflict. 
There is a manual solution to this: "yum update a b".  That makes yum 
think about both arches of the new b packages.  Of course, that requires 
me to know about the dependency on "b"... when all I'm going for is the 
new "a".

Shouldn't yum handle this better?  If pulling in a package, even just 
for dependency purposes, shouldn't it upgrade *all* architectures of 
that package on the machine, instead of just the one needed for the 
dependency resolution?
