I've run into this as well. Having confirmed that there are no handles on the file (it's only ever created and used by Cassandra), and having stepped through the code, I've concluded that something in the io (not sure if it's the jvm or the os) stack is lazy about releasing the file handle for 'RandomAccessFile's. I was able to get past these issues by setting a breakpoint after the call to close (on the file-to-be-renamed), waiting 30 seconds, then resuming the thread. Basically, Cassandra won't start on windows 7 in its current state.

I think it's not easy to review source code and eliminate such issues, but would like developers to keep in mind such issues in the future. We're also running a Cassandra cluster on Windows, but 0.7 beta1 (with similar issue, but for Commit Log) and waiting for 0.7 release to use it fully on production.
