* The following piece of code is taken from ns/nspr/src/md_HP-UX.c.
* In the comment for revision 1.6, dated 1995/09/11 23:33:34,
* 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.
