> stress.py cannot currently fully stress cassandra.  This is due to at least two reasons:
> 1. It does not use the accelerated thrift protocol (thanks jbellis)
> 2. The GIL is preventing concurrency
> To address this, I've modified it in a backwards-compatible way to support multiprocessing,
if available.
> Also, key_generator was providing floats instead of integers, causing the read test to
ask for keys that did not exist.
