We don't want to expose access to the carrier thread's locals as it 
could lead to all manner of breakage. There are number of discussion on 
this topic already in the mail archive,

If you use a custom scheduler, as Ron suggested, then you get a "hook" 
to run code on the carrier thread before and after the virtual thread 
task. The hook has a reference to the virtual thread so you may have 
enough for what you are doing.
