I am on Fedora 17 latest, but I've seen this problem with different kernels. 
Pretty sure from 3.5 something to 3.8 something. All Fedora flavoured. I will 
try vanilla soon.

What I am not sure is whether this behaviour was there from the start (on 
Fedora 17). I *think* it started to happen later on, which would mean a 
potential userland change somehow causes it.

Would that be at all possible with some mechanism?

What are these and how to create them?
