I assume you are refering to c/src/libchip/shmdr directory and poll.c and 
setckvec.c files there, right?

BTW: Is there any platform other than PSIM used to test this
functionality? What about x86/SMP, which we can emulate in Qemu? i.e. 
while fixing this I'd like to see if I break something or not...

Thanks,
