+# The failure script waits until it sees the 'mycopy.started' directory

+# If we don't wait, then SCons could detect our script failure early

+# The successful script waits until it sees the 'myfail.exiting' directory
+# that indicates the failure script has finished (with everything except

+# load happens to delay the failure script) and start another job before
