When using multicopy command in Codeploy to transfer large files from/to to planetlab nodes, we might face "timedout ssh" problem. This can be avoided by setting up the environment variable MQ_TIMEOUT to be a large value like 100000. So along with MQ_SLICE and MQ_NODES, we need to set this third environment variable.
