Pull run_in_vm() into a cleaner abstraction #46
Description
run_in_vm() is getting kinda hairy. It would be nice to pull it into a cleaner
abstraction. Maybe with some kinda OpenOptions
like builder to specify options.
A proper object would let us store more state and make the functions smaller.
Not sure if this should be ordered after #45 . Async would make a bunch of this stuff cleaner.
