I am not the author but 1024 happens to be the default maximum number of
open files for most systems(tm).

And yes if that assumption is wrong it will break and do strange things.

As I see it it's just a quick hack to get both values out of C without
further FFI tricks. Maybe I am wrong and Alex can explain the rationale
behind it, if there is any.

Kind regards,


May you be peaceful, may you live in safety, may you be free from
suffering, and may you live with ease.
