fakeroot doesn't intercept or alter fopen(). It'd be better to test
something
that is actually affected by fakeroot for a comparison. :)
fakeroot only traps things like stat and chmod, pseudo traps file system
opens
in general. So I would expect a pretty huge difference in this case.
Keep in mind that pseudo's overhead is all around opens, closes, and things
like stat/chmod; reads and writes are unaffected. Most real-world
programs that
manipulate files spend a lot more time reading or writing files than
opening
them, so a huge impact on file open time is relatively small on actual
execution
time.

Listen, get this. Nobody, with a good compiler, needs to be justified.
