Just out of curiosity, is there any talk of any implementation of D getting
precise GC in the near future?  It seems like when running programs that
actively use a large fraction of the 32-bit address space, the partially
conservative nature of D's GC can actually become a significant limitation.
On the other hand, the long-term solution is 64-bit.  Is precise GC
technically possible with D, and if so, is there anyone seriously thinking of
implementing it?

*delurk*
It's not possible without quite a bit of internal redesign, and there are  
still conceptual problems (e.g. stack layout of C library code).
I don't think it's in the plans at all.

I will be doing some reserch in the next few months as part of my graduate
thesis. Don't expect too much of this, it will be pretty limited (to
Linux+x86, only 32-bits probably). I'm setting up a blog to leave there my
advance, i'll post it here when it's online.

You should've seen her face. It was the exact same look my father gave me when
I told him I wanted to be a ventriloquist.
