So does this imply that if one is not using threads, such as, when compiling perl for DBD::Oracle, then the CoW option is unnecessary? Please elaborate when one would want or need to turn on CoW.

    My advice is to just turn it on and forget about it. It's not going to hurt anything. IIRC, the OS is responsible for implementing CoW for fork(), but Perl threads are a different matter, since it looks like a single process as far as the kernel is concerned.
