The code that does this involves setting itimers.Can you extrace a simple testcase from the itimer code? That would help a lot to track down this case. I'm a bit scared of emacs...
I was wrong about itimers. It turns out that emacs uses two different kinds of timers. One type is defined in C code and uses itimers, and the other type is defined in Lisp code. It's the latter that's involved here. So it won't be easy to make a test case in plain C.
I'm also finding that the order in which I do things affects whether or not the bug shows up. For example, if I start a shell within emacs before setting display-time-mode, the bug disappears. I'll keep looking at the emacs code, but maybe you'll be able to see something in the strace output.
