History
Konstantin Belousov 20b555e146 Do not run pmclog_configure_log() without pmc_sx protection. 
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.
