Represents the NOAA WCOSS clusters, Tide, Gyre and the test system Eddy.
Automatically determines which WCOSS the program is on based on the first letter of socket.gethostname(). Will report no ACL support, and no group quotas. Hence, the cluster should use group IDs for access control.
The production accessor is no longer a public member variable: it is now a property, which may open the /etc/prod file. The result of the self.production property is cached for up to prod_cache_time seconds. That time can be specified in the constructor, and defaults to 30 seconds.

Is this the WCOSS production machine?
The return value may change during the execution of this program if a production switch happened. In addition, the check requires opening and parsing the /etc/prod file, so the runtime is likely several milliseconds when the cache times out. To force a refresh of this information, call self.uncache() first.
