Actually, since Python has an incremental garbage collector,
it should in theory only require replacing the memory allocator with a
real time
memory allocator to make Python pretty hard real time capable. I think.

I also think I remember someone using Python for real time sample
by sample signal processing in Pd...

Efficiency is another story though
