afl master only run first cycle?

[zjuchenyuan]

master.log shows:

    Test case count : 2 favored, 0 variable, 100 total
       Bitmap range : 1011 to 1013 bits (average: 1011.50 bits)
        Exec timing : 138k to 310k us (average: 237k us)

[*] No -t option specified, so I'll use exec timeout of 480 ms.
[+] All set and ready to roll!
[*] Entering queue cycle 1.
[*] Fuzzing test case #0 (100 total, 0 uniq crashes found)...

In normal afl runs, there should be more logs?

also, the runtime CPU is so low...

For running 24 hours, the crash folder in sync/fuzzer-master/crashes is also empty for mp3gain 1.5.2-r2. And there is only one output file in sync/fuzzer-master/crashes for tiffsplit (libtiff-3.9.7)

my dockerfile:

RUN cp -R /usr/local/bin/afl-unix /usr/bin/
ADD utils.py /T-Fuzz/tfuzz

fix for utils.py are given in #12

seems like my own problem, afl cpu binding under Docker environment

I change the afl code to skip the binding, then it seems ok now
