// should it happen during, or after an interrupted transfer.

// Users writing to the buffer must first set the last byte of the buffer
// to non-zero (i.e. 0xFF). After (or during) the final write, set the
// last byte of the buffer to zero.
//
// Since the contents of the buffer must be a list of null terminated
// strings, the last byte must be a null when at maximum capacity,
// and it not being null means the buffer can be considered in an
// invalid state.
