Hi Gilles,
almost forgot to report this, didn't find time to dig into it. You can
easily check this with cyclictest: affinity mask set to 2, the test will
still schedule on CPU0.

If the user doesn't care about affinity explicitly, the skin should have
set the current task's affinity to XNPOD_ALL_CPUS on xnshadow_map (same
for xnpod_start_thread):
