Using attached importlib_sleep.patch, you can *see* the race condition with:

Example of output:
---
haypo@selma$ ./python -m test -m test_concurrency -v test_import
package: id=0x7fb497400d58
package: id=0x7fb49744d458
test test_import failed -- (...)

Lib/test/test_import/data/package/__init__.py is run twice instead of being run once. A lock is missing somewhere on the package module. |
