IIRC we had Timer-B enabled in VDI mode in the past, until someone
disabled it for performance reasons? So I'd rather not revert that now.
I think a better way to fix this is to add a TOS patch to disable that
loop in the affected TOS versions. We even already got a TP_VDIRES
condition that perfectly matches this case.
