A break may cause the session disconnect (and therefore agents destruction)
on a nested message loop. The runtime agent code is generally prepared to
handle this during evaluate, but the code outside of it may be not. Besides,
having a break before the console API installed is generally not what
user wants or expects, so just disable all breaks while installing the API.
