From 5c4ff3f00c6bd84ef0721c1077ee9c525daa68f8 Mon Sep 17 00:00:00 2001 From: Jeremy Evans Date: Thu, 8 Apr 2021 07:53:06 -0700 Subject: [PATCH] Document how to handle kill/terminate interrupts in Thread.handle_interrupt The kill/terminate interrupts are internally handled not as Exception instances, but as integers. So using Exception doesn't handle these interrupts, but Object does. You can use Integer if you only want to handle kill/terminate interrupts, but that's probably more of an implementation detail, while handling Object should work regardless of the implementation.
