Detached thread in D

[Ish via Digitalmars-d]

I am comping from C and POSIX threads. It is possible to start a 
posix thread in detached state by setting the arribute of 
thread_create to PTHREAD_CREATE_DETACHED
to recover the resources as soon as the thread terminates. Allows 
a large number of
threads to be created. Is there some thing similar in thread or 
fibers in D? Sample code will be appreciated.
