My working assumption is that the problem is a bug with the dynamic prioritization. The task receiving the signals calls sleep() after handling a signal and hence it's dynamic priority should end up higher than the priority of the task sending signals (since the sender never relinquishes the CPU voluntarily).
However, I haven't actually had time to look at the relevant code, so I may be missing something. If you understand the issue better, please explain to me why this isn't a dynamic priority issue.
