 * Reliability:
 *\li	This module deals with low-level byte streams.  Errors in any of
 *	the functions are likely to crash the server or corrupt memory.
 *
 *\li	If the caller passes invalid memory references, these functions are
 *	likely to crash the server or corrupt memory.
 *
 * Resources:
 *\li	None.
