The <code>OnlyOnceErrorHandler</code> implements log4cxx's default
error handling policy which consists of emitting a message for the
first error in an appender and ignoring all following errors.
<p>The error message is printed on <code>System.err</code>.
<p>This policy aims at protecting an otherwise working application
from being flooded with error messages when logging fails
