I can think of one way: go to a "thread pool" sort of arrangement where you
spawn off a thread to wait for the (non-)responses from network PCs in
parallel. This would reduce the worst-case traverse time from O(Ttimeout)
to O(Ttimeout/Nsize-of-threapool).
Of course, this would require massive changes to ls, and would unnecessarily
slow down and increase resource usage of the most common use case of ls,
namely getting a simple directory listing of files on a local disk.
