It wasn't.

I think the reason is that the next timer interrupt arriving while the
handler is running still is *much* more likely in virtual machines
because the vCPU does not get 100% of the of the physical CPU time
slice.

So on OVMF we will continue to need NestedInterruptTplLib.  I like the
idea to have a Null version of the library, so OVMF does not need its
own version of the driver just because of NestedInterruptTplLib.

take care,
  Gerd
