For the time being we have to do the explicit NOFS so in the code it's
a bit awkward. The hint is a function that takes transaction as
argument.

I'm working on the scope NOFS (marked by the transaction start/end), it's
intrusive, all over the code and there are some cases when I want to add
assertions that turns out to be tricky for some functions.
