Just curious. It's undocumented in the manual here.
Maybe someone who is familiar with the APC source code can explain?

It specifies a directory from which APC loads cache data on startup. In a large setup (think 100+ servers), this would allow you to forgo compiling php files. You could also supply your own compilations if you were somehow smarter than APC and the php compiler, or other kinds of default data.
Apart from this one occurence, it's unused. Unless you have one of the problems described above, you should not set it.
