Fine.

This looks like a kernel bug. I assume that your drive freezes, and the
driver does not abort, ignoring the requested timeout.

Could you make the wodim binary suid-root and retry the same thing?

It waits for the kernel to return. A program cannot abort a syscal just
so, so it's kernel's turn, no matter what the outcome is.
