 Review comment:
   It is good to add this assert but can we still keep this line ?
       if (!iter)
           return 0;
   It saves the router from a crash in production environment

> Parsing message annotations, especially on the inter router incoming link, are quite
> For example, in a simple standalone router test the time it takes on average (on my puny
laptop) to receive a message and hand it off to the core is ~1 usec:
> TestRouterA: link MyReceiver count=500000 rx=1.094 
> Compare that time to the same operation performed on the inbound router link on a two-hop
router configuration:
> TestRouterB: link MyReceiver count=500000 rx=7.035 
> On average it's 7x slower.  Most of this time appears to be spent manipulating inbound
message annotations.
> This Jira tracks work towards improving the performance of message annotation processing.
