Taking this tack would be a nice step on the way to permitting full
emulation of any arbitrary OS. The debugging hooks (ptrace()) would
probably be an example of a subset of what would need to be intercepted.
And since VSTa's ptrace() already parameterizes much of what kinds of events
should be intercepted, it seems like it'd be pretty easy to extend it to
permit, say, interception of certain classes of events.

Nice!
