On entry to a finally block, interruption/cancellation is
disabled/suppressed, and it remains disabled until the try statement is
exited normally, at which point the original state is restored.

However, the code in the finally block or in a function called from the
finally block could re-enable it for a section of code with the context
manager, but the context manager would save the current (disabled)
state on entry and restore it on exit.
