FYI, vmitools (LibVMI) does have support for memory events, just not
in the main branch. The events branch works properly for 4.1.x; I have
updated it to support 4.2, but due to other more pressing matters, I
have not had time to commit it to the main branch.

If you're interested in using the memory event facilities abstracted
via LibVMI, please let me know.
