The read method of nixio's file and socket objects both return an empty string when they reach EOF, not nil, causing the consumer to loop endlessly as source.file() never terminates. As there is no other situation in which an empty chunk is read, just change it to nil to terminate the consumer's loop. Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net>
