[issue47082] No protection: `import numpy` in two different threads can lead to race-condition

[Christian Heimes]

Christian Heimes <lists at cheimes.de> added the comment:

Python used to have a global import lock. The global import lock prevented recursive imports from other threads while the current thread was importing. The import lock was source of issues and dead locks. Antoine replaced it with a fine grained import lock in bpo-9260.
