I prefer this. If the app has a bug that causes one window to get stuck,
most likely that's the window the user cares about anyway, so the other
windows (temporarily) getting stuck is not a big deal. Also, if one window
is hogging the database then an asynchronously dispatched transaction is
going to be delayed indefinitely*, so some or all user operations in other
windows will not be able to complete, even if the other windows appear to be
responsive to events.

"He was pierced for our transgressions, he was crushed for our iniquities;
the punishment that brought us peace was upon him, and by his wounds we are
healed. We all, like sheep, have gone astray, each of us has turned to his
own way; and the LORD has laid on him the iniquity of us all." [Isaiah
