3 Checkes if the concurrent cache read/write works when the write is interrupted because of max-entry-size limits.
4 This is enhancement of 29c test, this test checks that a corrupted 206 response is correctly handled (no crashes or asserion failures)
5 This test is using a resumable response.
6 - with a profile, set max-entry-size to 1 (=1024 bytes)
7 - first channel makes a request for a resumable response
8 - second channel makes a request for the same resource, concurrent read happens
9 - first channel sets predicted data size on the entry with every chunk, it's doomed on 1024
10 - second channel now must engage interrupted concurrent write algorithm and read the rest of the content from the network
11 - the response to the range request is broken (bad Content-Range header)
12 - the first must deliver full content w/o errors
13 - the second channel must correctly fail
