This suggests using RETI is sufficient, and I don't need to make any special
allowances in the context switch code for the PMIC. So, I'm puzzled as to the
behavior I'm seeing, which is that ChibiOS thinks threads are switching (the
"currp" current thread pointer is definitely changing), but the actual
execution doesn't seem to change. That is, only the "main" thread seems to keep
running, and the little test thread never enters.
