Thread in detached state?

[Ish via Digitalmars-d-learn]

I was directed here from General list, so be patient with me. I 
am looking for syntax for creating a detached-state thread in the 
spirit of POSIX thread attribute PTHREAD_CREATE_DETACHED (the 
thread resources are released on termination and not when the 
main thread terminates - allows for a very large number of 
threads).

Sample code with call will be helpful.
