Peter Collingbourne 0ec5439ada LTO: Try to open cache files before renaming them. ... It appears that a potential race between the cache client and the cache pruner that I thought was unlikely actually happened in practice [1]. Try to avoid the race condition by opening the temporary file before renaming it. Do this only on non-Windows platforms because we cannot rename open files on Windows using the sys::fs::rename function.
