in thread export variable outside foreach

@lines being empty seems unlikely, since it was grepped out of the file.

I don't understand this point. Why would grep-ing the contents of the file make it likely that the  @lines array must contain something? (Or does this refer to a previous version of the posted code that was changed without citation?)

    My bad, I read "@lines is empty" correctly, but understood "@lines contains empty strings" :).
