This seems to be related to setting SPATCH_BATCH_SIZE to "0". It used to make things go much faster (if you had enough memory), but now seems to just consume tons of CPU. Setting it to "1" finishes the whole thing in ~13 minutes of CPU (~2m wall-clock). So that's at least a path forward, but in general I have been frustrated with operational aspects of coccinelle like this. -Peff
