Agreed. I think that things can be usually helpful. Now, I am not
really convinced that there is a strong need in running a VAX if you
are worrying about timing issues so this is a matter of balance. You
could get down to the same level of coverage with something as cheap
as a Raspberry PI or such. There are also configure switches that
emulate rather non-common behaviors, like --disable-spinlocks or
--disable-atomics that I'd rather never see gone.
