## Description The previous [PR](#1423) merged with intermittent testing stability: when the tests are run concurrently, some tests could fail based on timing. i.e.: https://github.com/OpenDevicePartnership/patina/actions/runs/23577664570/job/68653514272#step:5:1395 The idea is to put a lock on the test and extend the test to register and unregister within each individual test. - [x] Impacts functionality? - [ ] Impacts security? - [ ] Breaking change? - [x] Includes tests? - [ ] Includes documentation? ## How This Was Tested This was tested locally and on the pipeline to not trip on the same error. ## Integration Instructions N/A

Description
Patina internal CPU hosts the interrupt manager and other fundamental functionalities, which should not work on top of the allocator.
Admittedly, the current crate can support more advanced components that works on top of exception forwarding, but this should not be treated as a required dependency.
How This Was Tested
This was tested on QEMU Q35 and booted to UEFI shell.
