Blackhole user instantiation

[Radim Vansa]

Hello,

I'd like to reuse Blackhole in project aimed at benchmarking distributed 
systems (RadarGun [1]), but rather than just being tricky bastard [2] 
I'd like to ask if there's any info what black magic does JMH use to 
instantiate Blackhole properly and where be the dragons.

Note that RadarGun is not meant to be as precise as JMH, most of the 
benchmarked calls involve RPCs and generally take hundreds of 
microseconds or more. I use JMH for single JVM benchmarks, RG is 
convenient to orchestrate many nodes.

Thanks

Radim
