All threads created using std.thread, IIRC.

There is, don't use std.thread to start your thread ;). Be careful 
though: threads the GC doesn't know about should never have the only 
reference to an object allocated on the GC heap (i.e. allocated using a 
non-overloaded 'new').
In fact, it theoretically  shouldn't have *any* reference to an object 
created by the GC, since the GC is allowed to move objects and can only 
adjust references in the registers of a thread if it knows about the 
thread. However, the current GC doesn't move objects, so for now that 
should still be safe.
