[llvm-commits] [PATCH] lit/TestRunner.py: [Win32] Introduce WinWaitReleased(f), to wait for file handles released.

[NAKAMURA Takumi]

When wait() has finished, it tends opened handles (especially writing
stdout to file) might not be released immediately.
To wait for released, poll to attempt renaming.
