/*

Checkes if the concurrent cache read/write works when the write is interrupted because of max-entry-size limits.
This test is using a non-resumable response.
- with a profile, set max-entry-size to 0
- first channel makes a request for a non-resumable (chunked) response
- second channel makes a request for the same resource, concurrent read is bypassed (non-resumable response)
- first channel writes first bytes to the cache output stream, but that fails because of the max-entry-size limit and entry is doomed
- cache entry output stream is closed
- second channel gets the entry, opening the input stream must fail
- second channel must read the content again from the network
- both channels must deliver full content w/o errors
