It doesn't preallocate, and currently array appending in D is a slow or very slow operation.
If you need to speed it up, you can use a struct that performs this operation in a faster way, that's available in D2 in the Phobos, and in D1 can be found around (I have a version too for D1). Something like an Appender or ArrayBuilder.
