Hi Kevin,

   Thanks for your comments, and thanks especially for this updated
patch to address them.  I'm having a little bit of trouble with the
guest calling end().  The only way I'm able to get it working reliably
is for xen to call end() in __do_IRQ().  When the responsibility is left
to the guest, the shared interrupt seems to get stuck.  I'm still trying
to debug why this might be happening.  Thanks,

        Alex
