- * simple extension to the baos to try to use a ByteCache for its 
- * internal buffer.  This caching only works when the array size 
- * provided is sufficient for the entire buffer.  After doing what
- * needs to be done (e.g. write(foo); toByteArray();), call releaseBuffer
- * to put the buffer back into the cache.
