[comp.realtime] Faster Real-Time Unix Programming Possible?

Dear Fellow Real-Timers:

    Does anyone know of a way to schedule events at an interval which is
    shorter than the 10 millisecond resolution offered by the Unix 
    interval timer?  Specifically, I am running on an HP 9000 Series 800
    computer, which supports real-time processes using a priority mechanism,
    but provides no good way of scheduling rt events other than the 
    aforementioned interval timer.  I suppose if I had a peek at the kernel 
    source for the interval timer routine I could determine what physical
    resource is being used for timekeeping... Anyone done this?  I am quite
    willing to write a scheduler which uses the physical processor clock, if
    I can determine a way to access it.  Any help would be appreciated.
    E-mail is best, but I will be watching these bat-channels...
