+Subject: [PATCH] Limit hash table inserts after switch from stored deflate.
+
+This limits hash table inserts to the available data in the window
+and to the sliding window size in deflate_stored(). The hash table
+inserts are deferred until deflateParams() switches to a non-zero
+compression level.
