Great catch. I think also the thread Id tracker maybe isnt worth it if the GIL is reentrant. |

Since set-gil-thread-id! throws if CAS fails, this patch makes release-gil! exception safe by moving native call before it.
I only had one set-gil-thread-id! throwing CAS failure, so might not be worth it to spin on CAS failure, but at least shouldn't leave GIL in the bad state.
