Description

I've made a bunch of improvements to TestFileAppend2:

• Now has a main() with various command line options to change the workload (number of DNs, number of threads, etc)
• Sleeps for less time in between operations to catch races around close/reopen
• Updates to Junit 4 style, adds timeouts
• Improves error mesages on failure
