To avoid updating the schedtestfile while it is being read by a schedulability test program, the tracing daemon outputs two schedtestfiles, one kept for reference to the user (i.e., not deleted) and updated every time the daemon invokes a sched-test; the other schedtestfile is a temporary one, used by the invoded sched-test and deleted by it once its has read its contents
Fixed logging of schedulability test programs to sched_log_file instead of non_sched_file
