     - added AFL_EXIT_ON_SEED_ISSUES env that will exit if a seed in
       -i dir crashes the target or results in a timeout. By default
       afl++ ignores these and uses them for splicing instead.
-    - added AFL_EXIT_ON_TIME env that will make afl-fuzz exit fuzzing after
-      no new paths have been found for n seconds
-    - when AFL_FAST_CAL is set a variable path will no be calibrated 8 times
