In case spaces are generated lazily, and we're reading from a space that doesn't yet exist,
"read" a default value.

<p>
By default, the returned value is 0, which should be reasonable for all implementations.

@param size the number of bytes to read (the size of the value)
@param reason the reason for reading state
@return the default value
