It has always been the case.  In fact, I have a comment in the 
body of Thread.start() explaining this potential race and 
explaining the need for certain operations in that function.  So 
if there is a race, it isn't meant to be here and should be 
fixed.  I also just filed: 
https://issues.dlang.org/show_bug.cgi?id=13672 so some attention 
needs to be paid to this function anyway.
