What feedback system would that be? Wouldn't methane accelerate warming? From my limited knowledge of English semantics feedback - like in feedback loop - would mean some controlling function?

I'm fairly sure that harwoodleon is referring to positive feedback.

Negative feedback acts to oppose a change (think heating system temperature control). Positive feedback acts to amplify a change, and can result in runaway changes [1].

Accelerate warming -> more methane released -> accelerate warming -> even more methane released -> ...
