I do few modifications to run on linux, also add epoll() to kqueue() place.

Linux ubuntux64 4.4.0-57-generic #78-Ubuntu SMP Fri Dec 9 23:50:32 UTC 2016

./acc_test | grep "chk OK"
0:      socket(AF_INET, block)  ... lskt  accept  shutdown  chk OK, ret code:
22 - Invalid argument

43:     socket(AF_INET, nblock) ... lskt  shutdown  epoll  chk OK

shutdown() work every where!
close() does not work.
