Yes, but stdio can't handle non-blocking descriptors correctly, as I described in a previous note. I read RMS's suggestion as saying that since stdio can't handle non-blocking descriptors, it will do least harm by blocking on them. Clearly using stdio on a non-blocking descriptor is an error; however, as we see in the CVS case, sometimes that error is difficult to avoid.
