Maybe we could start losing most of the perf_ prefixes - it's all about 
perf here, so it does not really add much information, does it?

that would turn it into:

	if (target__has_task(target))
		return event__synthesize_thread_map(tool, threads, process, machine, data_mmap);
	else if (target__has_cpu(target))
		return event__synthesize_threads(tool, process, machine, data_mmap);

Another trick would be to combine (tool, machine) into a single helper 
struct (struct context *ctx?), if that is mostly a constant combination 
describing tool environment, which gets passed deep inside the guts of 
functions.

Thanks,
