I'm a total newbie to fuzzing and try to run the example in fuzzers/inprocess/libfuzzer_libpng, guided by the README.md under this directory. The fuzzer is running in my vm (Ubuntu 22.04 in VMware workstation). But how long should I expect this example to run, so that I can see something in the /crashes folder? I have open 4 clients to run the fuzzer concurrently for half an hour. The execution/sec is 400k+(I think it's relatively fast?) but the coverage seems to grow slowly (from 12% to 17%). I fully follows the instructions from the README.md. Not sure what goes wrong.
