By the way, I do think that GC performance can be improved significantly 
over where it is now, so don't take my other reply as an admission that 
GC is slow.  Also, I suspect that by the time D hits 1.0, GC performance 
will be much improved over what it is now.  This can be achieved a 
number of different ways, but the most obvious would be for the GC to 
ignore memory blocks that don't contain pointers.
