It's GPL, Apache, or EPL. I'm not sure about EPL, but I know that the 
former 2 are not convertible to Boost, so we couldn't accept a port from 
there.

Really though, the issues with D's GC are partly to blame from the 
language itself rather than the GC design. Having certain aspects of the 
language precludes certain GCs. Java as a language is much more 
conducive to more advanced GC designs.
