Doug Cutting commented on HADOOP-264:
-------------------------------------

There is an idiom for this hack.  See e.g., the static initializer blocks near the top of DataNode, DFSClient, DFSShell, JobTracker, TaskTracker, etc.  It's nice to keep these all uniform, with the same comment, so that, someday, we can easily remove them all at once.
