Issues with dtraceasm, and a workaround

[Henri Tremblay]

Sadly, I do not get the same result. When running from master I do get

# Processing profiler results: DTraceAsmProfiler Exception in thread "main"
java.lang.IllegalStateException: [kill: 37996: No such process

However, when applying the patch I still have the same error.
Running
sudo java -jar jmh-samples/target/benchmarks.jar Hello -wi 5 -i 5 -f 1 -w
1s -r 1s -prof dtraceasm

However, I do get the exact same issue with the PR. I did a clean install
between each run. I'm not sure if if I'm just stupid or something is
actually not working.

If someone has an idea. I'll debug slightly later.
