+// Dinit logging subsystem.
+//
+// Note that most actual functions for logging messages are found in the header, dinit-log.h.
+//
+// We have two separate log "streams": one for the console/stdout, one for the syslog facility. Both have a
+// circular buffer. Log messages are appended to the circular buffer (for the syslog stream, the messages
+// are prepended with a syslog priority indicator). Both streams start out inactive (release = true in
+// buffered_log_stream), which means they will buffer messages but not write them.
+//
+// The console log stream needs to be able to release the console, if a service is waiting to acquire it.
+// This is accomplished by calling flush_for_release() which then completes the output of the current
+// message (if any) and then assigns the console to a waiting service.
