I recently helped track down a bug exposed by a recent oslo.privsep release that added threading to allow parallel privileged calls. It was a segfault happening in the privsep daemon that was caused by a C call in a privileged Neutron module. This, as you might expect, was a little tricky to debug so I thought I'd document the process for posterity.
