I don't think it is a good thing to do. Of course GC is likely to 
have some memory left in hs internal pools but in general once 
you hit out-of-memory state last thing you want is not allocate 
even more.

More idiomatic D is to put `scope(exit) heapDeallocate(test);` 
immediately after allocation line.
