    It appears to simply speed up the delay case.

    One thing that I noticed though--the patch had the following line:

    if ((n == 0) && (inp == NULL) && (outp == NULL) && (exp == NULL)) {


    Would it be enought to just do the following?

    if (n == 0) {

    Given that if any of the fd_set pointers are non-empty, "n" ought to be
    non-zero, would this be a sufficient check?
