[rocket357]

datasize-cur is the CURRENT limit. datasize-max is what this class is allowed to raise the datasize-cur limit to:

$ whoami
rocket357
$ userinfo rocket357 | grep class
class staff
$ ulimit -d
524288
$ ulimit -d 710000
$ ulimit -d
710000

By default datasize is 512 MB, but I am allowed to raise it to datasize-max...
