If it's a symlink, then it *won't* be linked into any running process. The target of the symlink (libncursesw.so.5.5) may be, though.

Ah, I see. I must have seen the ".so" part, but then read ".so.5" or ".so.5.2" or something. OK, never mind then. :-) (They might be used if a compile is running, however that can't happen in the book as it is now.)
