Also just to add to Ron's comment is that there is ongoing effort to 
reduce the use of TLs in the JDK. That will help with the footprint when 
virtual threads are using standard APIs. It is also possible to create 
virtual threads that don't support TLs. It would of course be nice for 
that to be default but that makes it really hard to run a lot of 
existing code.
