Yes please.

I just noticed that I failed to support --safemode=<bitmask>, a new feature in
async-profiler that limits its tactics for Java stack recovery. It
looks to be intended
for production profiling (to limit exposure of unknown bugs or to workaround
new ones). I suggest we leave it out of the JMH integration.
