This may happen with other commands but so far I've only noticed it with adduser with Net::SSH 2.0.11.

Workaround: be sure to explicitly call rbox.disconnect when done.

Repeat:

Start an instance of ami-5394733a (ec2onrails/ec2onrails-v0_9_9_1-i386.manifest.xml).
Create an rbox instance as root
Call rbox.adduser(:delano) but don't call rbox.disconnect. It should hang.

The hanging was the channel waiting for input in STDIN.

Workaround: use useradd instead.
