Ok. A related matter: I use Linux a queueing discipline to delay 
outgoing traffic of an interface in dom0. However, if the network 
scheduler uses timer interrupts as a time source, the delay fluctuates 
quite a bit. According to the queueing folks, TSC as a time source 
should help.
But X86_TSC is commented out in linux*xen0/arch/xen/i386/Kconfig. No 
TSC for domains?
