consequences on the rest of the system, because the ISR runs with
The combination of an ISR (interrupts off) with a DSR (tasklet, task;
running with interrupts enabled) is the classical solution.

Yes. But mostly in closed source way. Most of the community efforts
have moved to RTAI, because that is a real open source project.

No, from time to time fsmlabs releases a new GPL version.

That's up to you to decide :-) The community feedback from RTAI is an
order of magnitude larger than with RTLinux, but that doesn't say
