already initialized constant WFKV_

Arrrgh. Squashing a DOS bug in Rack 1.3.4 was done by lifting some code from Ruby. But if you use Rack in your rails app, you’ll get a warning to the effect of “already initialized constant WFKV_”. To fix this, just revent back to Rack 1.3.3. I reverted back because this message is so darn annoying.

Of course, if you need the DOS protection in a production app, you’ll have to put up with Rack 1.3.4 in Production mode.
