Add deadlock test unit.
Fixed issue where no line were being published in the slow-requests. According to http://docs.oracle.com/javase/7/docs/api/java/lang/management/ThreadMXBean.html#getThreadInfo(long), the default getThreadInfo method returns a depth size of 0, so slow-requests were incomplete.
Revert extra spacing
