Socket and spawn()

[Andy Valencia via Digitalmars-d-learn]

I'm coding a server which takes TCP connections.  I end up in the 
main thread with .accept() which hands me a Socket.  I'd like to 
hand this off to a spawn()'ed thread to do the actual work.

    Aliases to mutable thread-local data not allowed.
Is there some standard way to get something which _isn't_ in TLS? 
 Or do I have to drop back to file descriptors and do my own 
socket handling?

TIA,
Andy
