unfsd was able to run several process in parallel since I think 1998. Note
it's multi-process not multithread, so it's a tad inefficient - but I
haven't heard of any problems in that area. unfsd was running on some
machines in the Suse R&D network as late as a few months ago, with 8
processes in parallel.
