Never mind, it was from running it in DrRacket. From the command line,
it doesn't block, so it parallelizes a bit, but it syncs a lot on
allocations. The code:

It uses two futures because that's how my randomized search for
something that worked turned out. I'm not sure whether that's better or
worse than one future.

After converting everything to Typed Racket and using no `for' macros,
I'm also getting a block on "prim_indirect" in the dummy renderer. It
would be nice to know which primitive it's referring to, especially
since I can't find anything but unsafe operations in the expanded code.

Just an update.
I've improved[1] a code a bit and it seems that values primitive has
went away: http://ompldr.org/vaGpweQ
but now it's [prim-indirect] stuff that blocks everything.
