You did and I didn't. Should have read "when NDEBUG is defined". Oops.

We define a few. base/Exception.h defines a RG Exception type, which is
derived from here and there. So they're not entirely foreign to RG.
Funny, while I was looking at that I discovered that we actually already
define and use the exceptions CommandCancelled and CommandFailed. They
don't try to do general cleanup, though. There are just three
parameterized commands like AddIndicationCommand that use them to bail out
when they can't get sensible parameters.
