It is permissible to install a child watcher I<after> the child has been forked (which implies it might have already exited), as long as the event loop isn't entered (or is continued from a watcher), i.e., forking and then immediately registering a watcher for the child is fine, -but forking and registering a watcher a few event loop iterations later is -not. +but forking and registering a watcher a few event loop iterations later or +in the next callback invocation is not. Only the default event loop is capable of handling signals, and therefore you can only register child watchers in the default event loop. |
