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());

The spawn function returns the tid, see the sample here: http://dlang.org/phobos/std_concurrency.html
