Modify ipxsocket regression test to create and close sockets several

times, with variable length sleeps between socket() and close().  This
will help to ensure that IPX/SPX timers fire while the sockets are
open, and hence have PCB's on the IPX pcb list, so that if timers are
going to stumble over PCB types they don't expect, it will happen as
part of this test.
