+ Enhanced to use millisecond based timestamps when writing log messages.
+ (RIC-627)
+
+ Enhanced to eliminate the reqirement that the file specified by the
+ RMR_VCTL_FILE environment variable exist when RMR is initialised. RMR
+ will correctly find this file if it is created after initialisation.
+ Further, if the environment variable is not given, the user may create
+ and populate /tmp/rmr.v at any time and the contents of this file will
+ be used as if it were supplied via the environment variable. This should
+ make debugging in existing containers easier.
