    The Single Unix Specification says:

    : The vfork() function has the same effect as fork(),
    : except that the behaviour is undefined if the process
    : created by vfork() either modifies any data other than
    : a variable of type pid_t used to store the return value
    : from vfork(), or returns from the function in which
    : vfork() was called, or calls any other function before
    : successfully calling _exit() or one of the exec family
    : of functions.

    So this one is (if I interpret it correctly)
    definitly bad code.
