Random exception

I'm seeing the following unhandled exception infrequently but (it seems) increasingly, perhaps due to increasing cbuzz load/traffic? I'm guessing there's a lock missing somwhere and two different client threads are competing over a structure:

Collection was modified; enumeration operation may not execute.

(followed by some debug info)

If this is something you want to track down, I can email the details the next time I see it. Otherwise, no big deal---it's transient, so pause-refresh solves the problem.

Yep... I know what it is, a refresh generally makes it go away. It's an issue with data caching that I hadn't originally anticipated years ago. Got it covered in v8 (which I promise will get here someday).

Righteous.
