     * The following piece of code is taken from ns/nspr/src/md_HP-UX.c.

     * robm says:
     *     This version has some problems which need to be addressed.
     *     First, intercept all system calls and prevent them from
     *     executing the library code which performs stack switches
     *     before normal system call invocation.  In order for library
     *     calls which make system calls to work (like stdio), however,
     *     we must also allocate our own stack and switch the primordial
     *     stack to use it. This isn't so bad, except that I fudged the
     *     backtrace length when copying the old stack to the new one.
     *
     * This is the original comment of robm in the code:
     *    XXXrobm Horrific. To avoid a problem with HP's system call
     *    code, we allocate a new stack for the primordial thread and
     *    use it. However, we don't know how far back the original stack
     *    goes. We should create a routine that performs a backtrace and
     *    finds out just how much we need to copy. As a temporary measure,
     *    I just copy an arbitrary guess.
     *
     * In an email to servereng dated 2 Jan 1997, Mike Patnode (mikep)
     * suggests that this only needs to be done for HP-UX 9.
