not in a serialized form). Hence, my position that apps that use python can't be forced to go through IPC or else: (a) there's a performance/resource waste to serialize and unserialize large or intricate data sets, and (b) they're required to write and maintain serialization code that otherwise doesn't serve any other purpose.

ention (unless documented otherwise) is that the app can make as many contexts as its wants in whatever threads it wants because the convention is that the app is must (a) never use one context's objects in another context, and (b) never use a context at the same time from more than one thread.

Re: 2.6, 3.0, and truly independent intepreters

ge, we have all kinds of options when it comes to multithreading). For example, recall that by throwing python in multiple dynamic libs, we were able to achieve the GIL-less interpreter independence that we want (albeit ghetto and a pain).

Re: 2.6, 3.0, and truly independent intepreters

arlier point about representing a company ready to spend real resources, please email me off-list if anyone here would have an interest in an open "CPythonES" project (and get full compensation). I can say for sure that we'd be able to lead with API framework design work--that's my personal strength and we have a lot of real world experience there.

And, for the record, I've said multiple times I'm ready to contribute monetarily, professionally, and personally, so if that doesn't qualify as the precursor to "code contributions from one of the participants" then I don't know WHAT does.

on't think you're talking > about python-level processes or threads. > Yeah, you have it right-on there, with added fact that the C and python execution (and data access) are highly intertwined (so getting and releasing the GIL would have to be happening all over). For example, consider and the dynamics, logic, algorithms, and data structures associated with image and video effects and image and video image recognition/analysis.

Re: 2.6, 3.0, and truly independent intepreters

ta structures situation (see my posts regarding real-time video processing). I'm not sure if you've followed all the discussion, but multiple processes is off the table (this is discussed at length, so just flip back into the thread history).
