Hmm..
I somebody willing to do a real patch against 2.1.23 with the latest timer stuff, and I'll apply it and we'll see what happens? It all looks good, we should be doing real well on timers with this setup.
Oh, one more suggestion: I don't think it's called for to try to be extremely clever about the cli/sti stuff. At least for the first version I'd prefer the straightforward approach that just uses cli/sti around the whole block of code, and then if we later find that there are problems we could try to "do them a few at a time and enable interrupts in between" approach. But I really don't think we need to add extra complexity until we _know_ that we'll need it.
(For hard real time this doesn't make any difference anyway, as that will take over the interrupt subsystem, cli/sti won't be a problem).
