/c/cs323/Hwk1/fiend ///
The staff solution will keep on running even after "fiend: opendir(///home/accts/aspnes/.esmtp_queue/.....) failed"

Should it exit after the "the depth of the depth-first traversal exceeds the number of file pointers available."?

i.e. in this case, exit the first time when it cannot opendir due to the lack of file pointers available.
