I'd suggest opening up an enhancement request. Assuming that that 
functionality exists across all of the various OSes, it can 
probably be added:

https://issues.dlang.org

You can also open an enhancement request for getting access to 
the OS thread handles, but my guess is that that wouldn't happen, 
because it makes it so that the Thread class no longer has full 
control, which would make it impossible to have any kind of 
@safety for Thread (though it doesn't seem to currently have any 
such annotations).

But if what you're looking for is thread functionality that is 
common across OSes, then there's a good chance that it's 
reasonable to add it to Thread, making it unnecessary to provide 
access to its innards.

In the meantime, I expect that you'll have to either use the C 
APIs directly or create your own class  which is a copy of Thread 
and tweak it to do what you need.
