bpo-32859: Don't retry dup3() if it is not available at runtime#5708
Merged
Conversation
os.dup2() tests for dup3() system call availability at runtime, but doesn't remember the result across calls, repeating the test on each call with inheritable=False. Since the caller of os.dup2() is expected to hold the GIL, fix this by making the variable holding the test result static.

os.dup2() tests for dup3() system call availability at runtime,
but doesn't remember the result across calls, repeating
the test on each call with inheritable=False.
Since the caller of os.dup2() is expected to hold the GIL,
fix this by making the variable holding the test result static.
