limited performance of stackful, preemptive, multitasking architectures

Remarkable : library research of concurrency models in user space has turned up ... zero common examples, except Erlang's BEAM VM ... of preemptively scheduled, stackful, multitasking architectures.

BEAM's famous limitations are the cold-starts, and fudgy burst capability, which prevents code from approaching C speeds.

Since I am learning C, I should some exercises to understand why this is architecturally impossible ( null hypothesis ).

In other news : Didn't think I'd have to pick up C++. But here we are 18 years after my first job in a bank with the title "quant". Malaysia, after all these years is STILL low-tech, and low-financial-sophistication.
