Thanks! Work in this direction is already well advanced. More precisely, the directory pypy/module/_stackless is obsolete and gone, and the pure Python module lib_pypy/stackless.py has been ported to use _continuation. (I wonder somehow why we had all this code in pypy/module/_stackless that seems not needed any more.) But it is not multi-thread-safe so far, which is probably an easy fix, using a thread-local instead of all these global variables initialized in _init() in stackless.py. Note also that there is a branch "continulet-pickle" that could do with help from someone with more motivation than me to finish this. So far you can pickle continulets, greenlets, and coroutines, but not tasklets. It looks messy because of early-optimization issues from stackless.py --- e.g. it would be much more natural for it to switch to the main tasklet every time it needs to do the scheduling and choose the next tasklet to switch to, instead of being clever and switching directly to the target tasklet; this "unwanted cleverness" prevents pickling from working at all, because it sees too much unrelated stuff in a suspended tasklet. All in all what I would be most happy with, at this point, is if someone would step up and finish porting and maintaining stackless.py. Ideally it would be someone that needs this code for his own projects, too. > Where can I find reference API documentation for channels and tasklets At the Stackless Python original web site.
