[Simh] porting simh to plan9

[Fernan Bolando]

hi all

i am trying to get simh running on plan9. so far after some minor
changes, i was able to compile it. After i tried booting pdp11 with
rtv53_rl disk it just sits there. I dont see any cpu loading so I am
not sure if it's just so slow or it's actually running. I can
interrupt the simulation and it will drop me back to simh prompt.

This is an overview of what I had to do to make it compile.
1. commented out all the nice() calls. I didn't think this is critical
to a get it running the first time.
2. commented out nanosleep()
3 commented out get_res call
4. I also had to had a bunch of fflush(stdio) in the console, because
plan9 io is buffered so you will not see the out unless you do that
everytime

anybody have an idea how to debug this?
