If you tell mdev to manage the /dev directory, and the kernel says that the 
node went away, mdev will delete it.  If you're saying the kernel will say a 
node went away when it didn't actually go away, that would be a kernel bug.

You don't seem to understand how mdev is for.  Maybe you want to be using 
something other than mdev, rather than complicating mdev?  And you haven't 
given a real-world example of where this is actually causing you a problem...

I'm confused...
