dup(2) returns the lowest numbered available file descriptor: if there's a discontinuity in the FDs allocation, this code is going to close only the FDs up to the first available FD. Imagine for example the following: open("/tmp/foo") = 3 open("/tmp/bar") = 4 close(3) Then dup(0) will return 3, and not the max FD.
