Are you saying I should be able to do this without modifying ISACaller source
at all?
I guess if there's a way to pause ISACaller execution, inspect mem/reg's, then
actually I don't need to touch ISACaller at all!

If there's not enough budget, I'm happy to split with Dmitry. Although your
work on syscalls will eventually come in handy towards cavatools, so raising
the budget is probably justified. Of course we'll wait on Luke's response.
