No, not "precisely".  It does more than you want.  E.g. it will also
affect other threads which could be running at the same time, or any
other piece of code that might run during this dynamic scope (e.g. while
debugging this code).

It's good we can use such a workaround when there's no other solution,
but let's not design things in a way that requires the use of such hacks.
