c glib is unable to handle client close unexpectedly

When using c_glib thrift server. Once a client connects to the server but does nothing (didn't send data to server) when being connected. If the client closed unexpectedly(such as being killed) at the moment, the thrift-work thread for that client wont't be closed and read the closed client sock fd in the server forever.

*I*t has been fixed in my branch, and will be tested and committed later if it runs well.
