Ok, I enabled faulthandler in the child process and I got the explanation: http://buildbot.python.org/all/builders/AMD64%20Windows%20Server%202008%20%5BSB%5D%20custom/builds/5/steps/test/logs/stdio multiprocessing's manager Server uses daemon threads... Daemon threads are not joined when the interpreter shuts down, they are simply "frozen" at some point. Unfortunately, it may happen that a deamon thread is "frozen" while it was doing a cyclic garbage collection, which later triggers the assert. I'm gonna replace the assert by a plain "if", then.
