However, I browsed the Mach documentation a bit, and found
task_set_emulation(). It is not documented properly, so I don't know
what it can do exactly -- whether it's for UNIX system call emulation,
or Mach trap emulation, or both... It *might* be a way to provide pseudo
task/thread ports without client-side changes.
After I read Exception Processing of Threads in "Chapter 3 Threads and Tasks" of "Mach 3 Kernel Principles", I believe it is only used for UNIX system call emulation even though I don't know the detail. for more detail, I guess we need to take a look at the transparent library they developed for the UNIX application program.
