The threads are considered IDLE and that's why you are running into this. The IDLE timeout (despite its name) has no concern if there is actually activity being done by the thread. It only looks at the amount if time it's been assigned from the pool.
IMO it's at best poor verbiage to call it and IDLE timeout value. They should either change the verbiage or implement functionality so that times out on the lack of actual thread activity.
A while back I filed an issue in the GF jira about this - feel free to throw a vote on it.

It's reflected in the responses, when trying with curl, for example, it would wait for all the time that the thread will take to execute the job, but the job is completed, the response fails; that. Because the HTTP request body is partially written by that time (before the job's started), curl just says "curl: (18) transfer closed with outstanding read data remaining". This only happens when response time exceeds 15 minutes (900sec). So, that pending interrupt actually cancels the request, once GF classes can get their hands on the thread.
