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