+
+Checkes if the concurrent cache read/write works when the write is interrupted because of max-entry-size limits.
+This is enhancement of 29a test, this test checks that cocurrency is resumed when the first channel is interrupted
+in the middle of reading and the second channel already consumed some content from the cache entry.
+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
+- both channels must deliver full content w/o errors
