Ok, I can now reproduce with setswitchinterval(). Here is a patch. There was a race between putting the new module in sys.modules and setting its __initializing__ attribute, so now __initializing__ is set before putting the module in sys.modules. Also, there was another race when retrieving a module lock from the locks dict (the weakref could be destroyed between the __contains__ test and the actual fetch).
