This would only work for large arrays I'm afraid, given the GC
implementation for D--it uses fixed-size blocks until the block
size is 4096 bytes or larger.  Also, the shrinking would be done
in chunks of 4096 bytes, so a fairly substantial size change would
have to occur for anything to happen at all.  That said, things get
a lot easier if moving the block is allowed.  Tango even exposes
a GC.realloc() routine which will do this for you.
