Check this portion of src/Overlay.cpp
static bool deviceIsCreated(const std::string& devicePath,
                             std::shared_ptr<uint64_t> bus,
                             std::shared_ptr<uint64_t> address,
                             const bool retrying)

I placed a comment describing the intent of the directory iterator. I 
have not seen the issue described on our systems, nor in QEMU (reported 
by another dev), so I'm not able to identify the issue.
