The API presented by operation.h expects milliseconds to be passed in. This patch drops the conversion from user-input microseconds-to-jiffies and from jiffies-to-milliseconds and instead converts directly from microseconds-to-milliseconds. The new minimum timeout will be one millisecond as opposed to one jiffy.
