  "message": "Properly refcnt child processes\n\nParents hold a ref on their children.  We didn\u0027t incref for this.  For\nforked processes, this was working, since we failed to decref.  Spawn,\nwhich decreffed properly, blew up.\n\nI think the ksched still had a copy of the proc, in this case, and it\ntried to run it.  The kref check (can\u0027t incref when 0) caught this.\n",
