What''s the problem you''re trying to solve?
If you just want to synchronize between VMs, there are a number of ways to
solve it without adding hypercalls:
* Share a memory page, and let the two VMs syncronize directly, without
needing to use the hypervisor
* Calling SCHEDOP_block on one VM, and then sending an event channel from
another VM
* Have a VM pause itself, and have another VM un-pause it
