Okay. Now that's just plain weird.
I use RHEL 5.3 x86_64, Xen 3.3.1 from Gitco, (dom0-cpus 1),
(dom0-min-mem 256), and dom0_mem=512M dom0_vcpus_pin. I've been using
both PV Linux and HVM Windows domUs on it and they can shutdown and
reboot just fine.

Any ideas where this bug is located? Is it the hypervisor, kernel, or
userland tools? If what you're saying is true (in that the bug affects
3.3.1 as well) then my only guess is that somehow my setup is immune
to this bug. I'd really like to know how.
