Noise words in file names

[johnousterhout]

Rather than using file names such as ArachneCreateTest, I'd suggest just using "Create". "Arachne" and "Test" are noise words that make the names longer without adding any information: everything in the directory pertains to Arachne, and every file is a test, no?

Also, it looks like you're not consistent: there is a file "NullYieldTest" that doesn't have the Arachne prefix.
