in thread 'unlink' seems to not work correctly ...

That is, if you're willing to pay the performance penalty for no_chdir, and in this case, it seemed unwarranted, since the workaround was so easy.

    performance penalty?
      Yes, no_chdir means that find needs to keep readdirring and stating longer and longer paths, repeatedly traversing the parent directories. Real find, like the default File::Find, uses chdir to ensure that the readdir and stats traverse the minimal number of inodes.
