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. -- Gary R.
