There was a race where: - The LockFileManager tries to own the lock file and fails. - The other owner then releases and removes the lock file. - The LockFileManager tries to read the owner info from the lock file but fails now. In such a case have LockFileManager try to get ownership again, instead of error'ing out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203138 91177308-0d34-0410-b5e6-96231b3b80d8
