Test case

Description of Problem:
I am trying to connect to a socket in a background thread. If the socket fails
to connect, it causes mono to abort. On .Net this continues to try and connect
to the socket.

Steps to reproduce the problem:
1. Run the attached sample programs.


Actual Results:
(gdb) run Test.exe
Starting program: /home/staff/jschambe/monosvn/install/bin/mono Test.exe
