9fe00836f7 fix stack mapping code to do as many passes as necessary 
Previously, we had been doing exactly two passes over the event log to
caculate the stack object reference map at each trace point.  It turns
out the correct number of passes depends on how many incorrect
assumptions we make about what the stack looks like at instructions with
multiple predecessors (i.e. targets of jumps and branches).

Each time we detect we've made one or more incorrect assumptions during
a pass, we must do another pass to correct those assumptions.  That pass
may in turn reveal further incorrect assumptions, and so on.

71e7a6d796 Simple non-blocking client and server example programs. The client 
actually simulates blocking IO by implementing a Socket OutputStream, and
sends a file to a port.  The server listens on a port and dumps the output
to test files.  Together, these classes can be used to send a file from
a client to a server machine over a socket.
