Does it make sense? I do not mind submitting a patch for this issue if you don't currently have the spare cycles, just let me know if we are in agreement in terms of understanding the issue and I can submit a patch that blocks "app signals" in every place that uses the killlock. Probably could also remove the pthread_self() special case that you referenced earlier in the thread but that would be a second patch. Thank you, Hydro
