Yes, I also think for long-running memory-hungry server-stuff the 
current conservative GC is a show stopper. Some people are 
working on a concurrent and a  precise GC. Then parallel and 
concurrent and incremental and generational and whatnot GCs will 
be explored. The point where it gets interesting for these 
server-apps is not clear though.

As far as I know those other GCs are not ready for prime time 
yet. For sure, there is no other GC shipped with the current D 
2.064.2.

Oh, and keep nagging! We need to hear about showstoppers, so we 
can fix them! ;)
