Sometimes it’s useful to handle the exception somewhere near its origin so you can close related resources, lockfiles, etc. without needing a VB6 style “On Error GoTo X” global error handler that has to account for all different contexts under which the exceptional situation might have occurred.

Your process can crash or be killed at any moment anyway. Depending on in-band cleanup is not reliable.

Sure, but there are many cases where you don't have to halt because you can cleanup and carry on.

... That seems like a pretty accurate description of how exception handling mechanisms are implemented under the hood. :)
