Review comment:
I am not clear what is the motivation for changing this.
The following file name generation is not only based on `tempDirs.length`
which is only for the parent dir, and the specific sub name is from
`randomString(rnd)`, so I think it does not very make sense to limit the retry
times directly based on `tempDirs.length`.
