iodcstrategy() maintains a cache for READ performance (tapes are supported
here, and alternatively would need to rewind). WRITE code exists, but was
always wrong -- it writes the cache-buffer to disk, rather than the provided
write-buffer. Copy the write-buffer into the cache, and invalidate the cache
completely so that future reads start from scratch.
