Right now nothing. I used to work with HPUX with "Real time Extensions". One of the things we could do is shut off interrupts for certain processes.
There was a subset of systems calls we could use while in this realtime mode (A lot of unix system call really rely on interrupts, and the whole OS is built on them..).
I think interrupts started from hardware signals, but were expanded to include software.
