    1616Multiprocess architecture needs multiprocess debugging. Usually we are interested about what is happening in the web process. To debug the web process you need a way to attach to it. You can tell gdb to attach to a given pid at startup with the --pid=$pid switch or you can use the attach command. In newer versions you can use "set follow-fork-mode" command as well (i.e. "set follow-fork-mode child" means that the debugger will automatically attach to the child process on a fork.) For special cases some helper functionality had been added:
    1717    * If you need to see what's going on at program startup (for example you are debugging an initialization crash) then attaching is not good. That is the motivation behind http://trac.webkit.org/changeset/70760. Read the Changelog and follow the instructions if you need to stop execution at startup. (Tip: use the -s switch of pidof at the end of the command to restrict the output to the main thread pid.)
    18     * There is a minor issue with the "set follow-fork-mode" command: you cannot interrupt the web process and return to the debugger by pressing Ctrl-C  because the it will immediately terminate (due to how we set it up). To work around this behavior, see http://trac.webkit.org/changeset/81507.
