Oh this is interesting. I read in the documentation that custom blocks have tag Custom_tag, which is higher than No_scan_tag, and thus they aren't scanned by the GC. Indeed, even trying to Gc.finalize on the object inside the lazy seems to have no effect.

There are a number of bugfixes to the existing bindings as well. I have an experimental version of xenopsd that successfully uses the new bindings. An earlier version of the first half of the series was submitted to the last by Ian Campbell on
