/*
Checkes if the concurrent cache read/write works when the write is interrupted because of max-entry-size limits
This test is using a resumable response.
- with a profile, set max-entry-size to 0
- first channel makes a request for a resumable response
- second channel makes a request for the same resource, concurrent read happens
- first channel sets predicted data size on the entry, it's doomed
- second channel now must engage interrupted concurrent write algorithm and read the content again from the network
- both channels must deliver full content w/o errors
