Thanks, I appreciate it.

Yeah, I worry about that too, especially since the native/c tests all pass.  
Although, considering my poor Python skills, Cython could be just fine but 
rather it is my binding/glue code which is busted.

I think it may be time for me to go bug our ARM people for access to a system.  
Last time I checked they didn't have +3.8 booting on the dev systems but they 
may have them running now.
