This last part sounds like a bug -- transaction guards are supposed to
nest, so that if we are already in a transaction all that they should
do is increment a variable somewhere.

Fixing this would help with some of your later concerns about removing
transaction guards as well, since there should never be any reason to
remove a transaction guard...

You might also want to look into the "checkpoint" (IIRC it's called
that) functionality, if you're thinking about automate stdio and
transactions.

must debate everything, and there would be no end to the discussion).
