I believe the intention has been all the time that initializing a 
context using an IR packet would start with a clean slate, as if the 
channel was just created.  I.e., this is a new context, even when a CID 
is being reused.

I'm too busy to do the analysis (read: dusting off brain cells) right 
now:
Do we have any case where we need to maintain previous state beyond an 
IR packet?

Gruesse, Carsten
