Protothreads

Protothreads

In computer science, protothreads are a low-overhead mechanism for concurrent programming.

Protothreads function as stackless, lightweight threads providing a blocking context cheaply using only two bytes per protothread. [http://eigenclass.org/hiki/about Eigenclass] performed a comparision of protothreads against POSIX threads, and found a 400x improvement in speed [http://eigenclass.org/hiki/threadring-with-protothreads] .
