Well, it is used in other places too, like in figuring out _once

Are you calling clearstatcache() manually anywhere? That blows
away the entire realpath cache and completely destroys your
performance, so you will want to avoid doing that very often.
Based on what I've seen, if the realpath cache gets filled it just
quits caching rather than pruning. That seemed odd to me.
There was also an issue that Dmitry had fixed in 5.3 a month or so
ago where it was caching false finds and filling the cache up more
quickly than necessary. I found this out through a quick extension I
wrote to view the contents of the realpath cache. If anyone wants to
clean this up for inclusion in the core, I'd be more than happy to
have it there. You can grab a copy from my Git server:
