Yes, I am using the C library.

This is less a question of ephemeral node behavior and more a question on
how to properly watch ZNodes. Unfortunately I don't know the C library at all
(it looks like that's what you're using). I can only say that writing code that
correctly watches a ZNode is not trivial. Of course, there may be a bug in the
C lib - I know it's not maintained to the same level as the Java lib.
