If two 'git sparse-checkout set' subcommands are launched at the same time, the behavior can be unexpected as they compete to write the sparse-checkout file and update the working directory. Take a lockfile around the writes to the sparse-checkout file. In addition, acquire this lock around the working directory update to avoid two commands updating the working directory in different ways.
