While agree on principle, both calling the garbage collector, tuning the 
allocators, or moving the creation of a sub-binary to a temporary 
process in the current contexts are workarounds over the current 
limitation where the most natural pattern results in a memory leak.

You're suggesting another pattern that conflates code compared to its 
ideal format, which just leaks right now. The problem is not the 
workaround, it's needing it in the first place.
