I couldn't find a wrapper to get current thread id.

There is Thread.getThis but the address it returns is the same for all threads as explained here (http://ddili.org/ders/d.en/concurrency.html) so it's not useful for logging.

How about adding this:

auto getTid() to class Thread

Implementation on OSX:

mach_port_t tid = pthread_mach_thread_np(pthread_self());
