Need quick and reliable thread or timer

I am writing an audio driver and would like to perform a very small amount
of work at least every millisecond, with no more variance than a tenth of
a millsecond. What mechanisms can be employed here? Can a thread be
used? Can the priority be raised high enough to ensure it is running once
every millsecond? Is there a timer as accurate as a Time Manager Task in
OS 9?

Thanks,

Sean
