8317801: java/net/Socket/asyncClose/Race.java fails intermittently (aix)

[varada1110]

The preClose() method internally calls the dup2() system call. If there is a dup2() call on a file descriptor on a thread while another thread is blocked in a read/write operation on the same file descriptor, then the dup2() call is known to hang. Currently, preClose() experiences a hang because we call dup2() before killing the reader/writer thread(s). The workaround is to first kill the reader/writer thread(s) and then do the preClose() sequence. This reordering in the different channel implementations resolves the problem.
