title: Are strings interleaved when using ap_log_error() in a prefork apache?
body: <p>Using <code>printf()</code> and <code>fprintf()</code> from an apache module in a pre-fork apache seems to interleave the logs in error_log. Would using <code>ap_log_error()</code> instead of, say, <code>fprintf(stderr, ...)</code> fix the interleaving?</p>
