    A more-conservative workaround for Cygwin SIGCHLD issues. · fa55d2aa

    * callproc.c (Fcall_process):
    * process.c (create_process):
    Make sure SIGCHLD is caught before we fork,
    since Emacs startup no arranges to catch SIGCHLD.
    * process.c (lib_child_handler): Initialize to null, not to
    (catch_child_signal): Allow self to be called lazily.
    Do nothing if it's already been called.
    Assume caller has blocked SIGCHLD (all callers do now).
    * emacs.c (main): Do not catch SIGCHLD here; defer it until
    just before it's really needed.
    * nsterm.m (ns_term_init): No need to re-catch SIGCHLD here,
    since it hasn't been caught yet.
