If you were using the BSD sockets layer, the solution would be to use
the select() function to wait for completion of connect operations
without blocking, while also servicing existing connections.  There is
no select operation at the netconn layer, but as the sockets layer
implements select using the netconn layer functionality, you should be
able to look at what it does and do something similar.
