Summary:
The main motivation is by making this change, we can log panic message here too:
https://www.internalfb.com/code/fbsource/[4a662228cd8bdf2bdf9b760e705cc9958f85e55c]/fbcode/monarch/hyperactor/src/panic_handler.rs?lines=47
it currently does not and caused quite some confusion for me, since I thought there is a bug in the panic catching logic.
