The "depsolving problem" was from 3.2.1. It's fixed on 3.2.2.
I was actually preparing to jump to 3.2.2 immediately after that, but
when I compared "list updates " from 3.0.6 to 3.2.2, I got the bad news.

Comparing 3.0.6 to 3.2.2
3.0.6 :
========================
# time yum list available  > /dev/null
This system is not registered with RHN.
RHN support will be disabled.

real    0m4.860s
user    0m4.548s
sys     0m0.216s

# time yum list installed  > /dev/null
This system is not registered with RHN.
RHN support will be disabled.

real    0m0.403s
user    0m0.320s
sys     0m0.080s
========================

3.2.2 :
========================
# time yum list available  > /dev/null
This system is not registered with RHN.
RHN support will be disabled.

real    0m22.164s
user    0m19.513s
sys     0m2.540s

# time yum list installed  > /dev/null
This system is not registered with RHN.
RHN support will be disabled.

real    0m0.407s
user    0m0.324s
sys     0m0.076s
========================

So it seems that on "yum list available", 3.2.2 is slower. This is with
the same plugins activated : yum-rhn-plugin-0.4.3-2.el5,
yum-priorities-1.0.4

Changing to yum-priorities to the one from yum-utils-1.1.6 doesn't show
any difference :
========================
3.2.2 :
# time yum list available > /dev/null
This system is not registered with RHN.
RHN support will be disabled.

real    0m22.235s
user    0m19.729s
sys     0m2.376s
========================

However, disabling plugins shows 3.2.2 is faster.
========================
3.0.6 :
# time yum list available --noplugins > /dev/null

real    0m2.310s
user    0m2.032s
sys     0m0.192s

3.2.2 :
# time yum list available --noplugins > /dev/null

real    0m1.454s
user    0m1.120s
sys     0m0.196s
========================


So I'm guessing that 3.2.2 IS indeed faster for some operations. I'm not
sure why the priorities plugin make it solwer than 3.0.6. Since we use
priorities plugin on all systems, I guess I'd stick with 3.0.6 for now.
OS/Package versions, in case it matters :
RHEL 5
rpm-4.4.2-37.el5
python-2.4.3-19.el5
sqlite-3.3.6-2
