Not to work around the OS limit - to work around the unwieldiness of
large fdset's. This is just an application of the same
divide-and-conquer strategy that applies to binary search, trees, and
other such log(N) algorithms. Just because an OS allows a single process
to use thousands of file descriptors does not mean it's a good idea to
Why wouldn't you apply the same divide and conquor strategy
inside a process ? (e.g. by using threads, or multiple descriptor
do so. At the kernel level it's going to be more efficient to deal with
a cluster of average sized processes vs a single process with a huge
context. Eventually something is going to come along that causes the

doing nothing besides occupy address space, whereas a cluster of
processes will provide more scheduling opportunities for useful work to
get done; even if one process completely blocks, other processes may
Hmm...what you are descibing here sounds like a broken scheduler.
Do you know of any OS'es in use today that have such a scheduler ?
