Currently, benchmarks always run on background thread. It would be great if a new Toolchain and Executor are run on the same thread, or a property is added to existing toolchains/executors to control whether a background thread is created or not.

Actually, just came across this today - we need to benchmark with a native database ORM (Realm), which requires that its instance is created on the same thread that runs the code. This fails with benchmarkdotnet as-is right now.

Can't you just set it up in [GlobalSetup] (and tear it down in [GlobalCleanup])?

With the default toolchain no threads are being created and every benchmark is executed in a dedicated, standalone process.
