> Limits statically loads a JobConf, which incurs costs of reading files from disk and
parsing XML.  The contents of this JobConf are identical to the one loaded by YarnChild (before
adding job.xml as a resource).  Allowing Limits to initialize with the JobConf loaded in YarnChild
would reduce task startup time.
