When running a "while : ; do : ; done&" loop in dom0, I saw that
none of the guest domains were receiving any CPU time for seconds,
quite possibly more than a minute.

The guest domains did not get significant CPU time until the
inifinite loops in dom0 were terminated.  I am currently reading
the EDF code to figure out what's going on, but would appreciate
hints that shorten my search...
