-/* The linux kernel 2.4 getpid implemention always return the pid of the
-   thread subprocess and not of the main process, the NPTL implementation
-   with a Linux kernel 2.6 kernel return the pid. So when possibly
-   there is the wrong implementation of getpid, we save the pid at startup.
-   FIXME: when our Linux base-line is above:
-        + Linux kernel version 2.6 or higher; -> clone() for NTPL
-        + glibc2 version 2.4 or higher; -> No longer LinuxThreads, only NPTL
-   Then we get a working getpid() and can remove this hack.
-   FIXME: getppid is also wrong in this situation
