core.thread.Thread.start is marked as "nothrow" but documentation says it throws

final nothrow Thread.start()

Looking at the code, no "throw new ..." is seen, but the function 
"onThreadError" is called
which has "throw" in it.

Most weird thing is that "onThreadError" function is marked as 
"nothrow" but it still throws.

I would think that yes, maybe the compiler might not be able to 
see it because throw is found
in another function, but how come "onThreadError" throws with 
nothrow.
