Re: MSI interrupts

Remember only the lines participating in the event count.  For
example, say one had sprintf() inside the event.  None of the
lines touched by sprint() are participating in the event,
and are not counted against the 8 cache lines available.

Hmm... so if I need to add a "participating line" to which I need to
store but that I don't need to read, I still need to do a "useless"
`esmLOCKload` before the (normal) store, just to mark the line as
participating in the event?
I guess it's a rather rare need.
