If you've for example an application with a GUI. Every time bigger
objects are pickled/unpickled the complete GUI blocks.
Or if you've a server application with multiple network connections and
the application should have a guaranteed response time, then it is
impossible if one single client

This is a fair comment.
Please open an issue on
The GIL must be held to allocate memory for Python objects and to
invoke the Python code to deserialize user defined picklable objects.
I don't think there is a long span of time where the code could leave
the GIL released. The Python implementation is just pausing to let
other Python threads run,
Hi,
the old and slow python implementation of pickle didn't block background
thread.
But the newer C-implementation blocks other threads while dump/load is
running.
Wouldn't it be possible to allow other threads during this time?
Especially could load/loads release the GIL, because Python

This is roughly what Eric's subinterpreters approach tries to do.

On the other hand Windows has a higher need for a better multi-core
