I think so. If I've understood you, then this mutual exclusion would
prevent me from having to worry about whether a packet processing event
that's reading a data structure is in fact getting a coherent version of
the data structure (since a write handler might be mucking with the data
structure at the same time the packet processing code needs to read the
data structure).

Thanks!
