IRIX emulation, getting there.

[Miguel de Icaza <miguel@nuclecu.unam.mx>]

This is my next show stopper:

   There is a misterious fcntl call in the IRIX Xsgi server:
it is called with the F_ALLOCSP flag, what is this flag used for in
the X server setup code?  

Cheers,
Miguel.

   Unsolved misteries -- update

   The magical address at 0x200000 in the IRIX executables contains
   a one zeroed-page, for now I have mapped an empty page at this
   location on every IRIX program that is ran on the system.

   Both the usinit() test and the Xsgi server can continue execution
   under this scenario now, but it is still hackish.
