One easy way of testing is to use the tools/tests/xen-access test program which 
exercises mem_access and thereby mem_event. It is fairly easy to run. Bring up 
a domain and execute " xen-access <domain_id> write|exec". But I understand if 
you are under time constraints and cannot do it. If you Cc me on these patches, 
I will gladly test them for you.

Thanks,
