The r195005 unlocked pmc_sx before calling into pmclog_configure_log() to avoid the LOR, but it allows flush or closelog to run in parallel with the configuration, causing many failure modes. Revert r195005. Pre-create the logging process, allowing it to run after the set up succeeded, otherwise the process terminates itself.
