** The vdo-stream allocation API:s have the following limitations:
** 1. Buffer alloc/unref are fully synchronous and will BLOCK.
** 2. Buffer alloc/unref does not support encoded streams (vdo_format_is_encoded).
** Use the stream global setting "socket.timeout_ms" (int32_t) to control maximum blocking time.
