Fixed Bug: typo error, i char missing on first if statement
Merge pull request #61 from albertofalzone/master

Typo error fix
Correct wrong formatting.
Fixed a bug in res which caused the select() timer to be incorrectly
computed and making res child loop.
Make sure to sleep for at least 1 second in select if no descriptors
are ready for IO.
Simplify the res timer.
