I don't think that's it. If you have a memory limit set, then there's a
factor of 2 involved, but that doesn't apply when you don't have a
memory limit.

For "Racket", do you mean version 5.0? If you mean later versions from
git, I wonder whether commit 41d1daf53 from June 1 is relevant. (Commit
0e664e7c0 is needed along with 41d1daf53 under Windows.)
