+- Issue #24891: Fix a race condition at Python startup if the file descriptor
+ of stdin (0), stdout (1) or stderr (2) is closed while Python is creating
+ sys.stdin, sys.stdout and sys.stderr objects. These attributes are now set
+ to None if the creation of the object failed, instead of raising an OSError
+ exception. Initial patch written by Marco Paolini.
