Here is the next round. We have three queues now. All incoming messages are queued in msg_list and if nothing is missing we move it to the running_list and exec in the background. If the exec comes back, it removes the message from the running_list and frees the message. Before we exec, we check the running_list if there is a udev running on the same device path. If yes, we move the message to the delay_list. If the former exec comes back, we move the message to the running_list and exec it. The very first event is delayed now to catch possible earlier sequences, every following event is executed without delay if no sequence is missing. The daemon doesn't exit by itself any longer, cause we don't want to delay every first exec. I've put a $(PWD) for now in the Makefile for testing this beast. Only the local binaries are executed, not the /sbin/udev. We can change it if we are ready for real testing. And SIGKILL can't be cought, so I removed it from the handler :) 06:58:36 sig_handler: caught signal 15 06:58:36 main: using ipc queue 0x2d548 06:58:37 message is still in the ipc queue, starting
