    We could of course use iret to return to the regular kernel stack, and
    do the schedule from there.

    So instead of doing the manual stack switch, just build a fake iret
    stack on our exception stack. Subtle and somewhat complicated. I'd
    almost rather just do a blind iret, and leave the 'iret to regular
    stack' as a possible future option.
