This is an addition of the post Producer/Consumer in Python I wrote earlier. It’s just the same example rewritten with py.magic.greenlet. Greenlets, tasklets, micro-threads, coroutines are basically the same thing: suspending and resuming a function in multiple points is the core feature we need.

Like Hello World in imperative programming the Producer/Consumer problem is one of kind of program everybody has wrote once in a lifetime. It’s one of the toy examples in concurrent programming demonstrating the basics of synchronization. Basically there’s a shared buffer, a producer entity and a consumer one. The producer generates some data and puts [...]
