Sorry, this review fall of my radar. Patch and tests look good, marking as
ready to commit! Thanks!

> Project: Cassandra
> Issue Type: Bug
> Components: Tools
> Environment: 1000 M1.Large Ubuntu 12.04

> Nodetool status on a 1000 Node cluster without vnodes returns in several
> seconds. With vnodes on (256) there are OOM errors with the default XMX of
> 32. Adjusting the XMX to 128 allows nodetool status to complete but the
> execution takes roughly 10 minutes.
> Tested
> {code}
> XMX | Status
> 32 | OOM
> 64 | OOM: GC Overhead
> 128 | Finishes in ~10 minutes
> 500 | Finishes in ~10 minutes
> 1000 | Finishes in ~10 minutes
> {code}
