You're assuming the program uses finally/scope exit blocks to do
shutdown logic. This is not always the case. A library shouldn't force
certain development styles.
I do and within the reason. Doing graceful shutdown logic in
scope/finally/destructors or what the heck the top-most catch(Exception)
is not just a good practice. Otherwise an unexpected exception on the
way up leaves debris and destruction behind, and the whole point of
graceful shutdown is lost.
Yup, one can provide an alternative way of shutdown, yet one still has
to think of unexpected exceptions.
