You see, we didn't know that anyone was using fakephp for real work.
It's marketed as being a way for developers to test their device drivers
with hotplug slots even if they don't have a real hotplug machine.
If we'd known, we'd've done a better job.

BTW, cut the crap about "Sometimes I just want to give up on Linux".
We're putting in a lot of work that you get to use for free.  That doesn't
give you the right to be abusive.  And if you stopped using Linux, we'd
have one fewer person complaining, so I don't personally find it a huge
motivator to drop everything and attend to your whims.

There is no race condition.  You can't remove a fakephp slot.

Hey, I have a great idea.  Why don't you help instead of just bitching?
