Yup.  However, an annoying problem still exists with Buffer.  Basically, 
this class maintains a void[] reference to a block of memory allocated 
as a byte[].  However, if the block is resized for any reason, the type 
doing the resizing is used to determine whether the newly allocated 
block contains pointers.  I've been meaning to change the Tango runtime 
and GC to preserve array block attributes across reallocations, but it's 
a somewhat involved process and I haven't gotten to it yet.
