| Thread-topic: | [PATCH] ioemu-remote: check shutdown_requested timely. |
After a recent merge of the ioemu-remote tree several weeks ago, I find in main() -> termsig_seup(), ioemu sets a SIGHUP handler that sets a global variable shutdown_requested to 1, but ioemu doesn't check the variable and as a result, ioemu wouldn't terminate when xend sends a SIGHUP to it; finally xend has to send a SIGKILL to it in 10 seconds. The small patch adds a check to terminate ioemu timely. Thanks, -- Dexuan
