Editing Draft:Elixir/bzip2-ex (section)

==High- or low-level integration?==
We already chose the "hard landing" by writing a new library in the first place, but there's still an opportunity for making life sort of easy again, by choosing one of two APIs provided by libbzip2, either the high-level<ref>https://sourceware.org/bzip2/manual/manual.html#hl-interface</ref> interface which opens a file and returns the decompressed contents, or the low-level<ref>https://sourceware.org/bzip2/manual/manual.html#low-level</ref> interface for maximum interactivity, which is called with tiny bites of data, shares its memory with the caller, exposes an internal state machine, and offers your humble developer many forms of additional stimulation.

There were a few considerations here, and in theory the high-level interface would have made a perfectly acceptable binding.  However, this would be a single call to decompress the world, and control flow wouldn't return to Elixir for several hours.  This pretty much defeats the purpose of writing a binding library for a concurrent virtual machine.
