Low-level API: Don't log just before raising an exception

Browse Source 
The only logging we should do is when we've encountered a problem *and
we've dealt with it ourselves*. When we're raising an exception, it
should be up to the caller to decide whether to log anything about it.

Anything else is just rude.
