The current implementation of vectors is not as fast as it could be,
as it forces a fullsweep (major) garbage collection as soon as an vector
update has created pointers from the old generation heap to the new
For some uses, vectors will still out-perform other data structures.
We hope to make the vectors faster in a future release by implementing
a proper write barrier in the garbage collector.
