Implemented fix as suggested in Bug 3973 The MapiSocket object now supports getting and setting the socket timeout, even before the TCP socket is created. Also improved the close() method to continue closing all opened resources, even if one of them failed to close. To set the socket timeout specify it in the JDBC URL, for example: jdbc:monetdb://localhost:50000/demo?so_timeout=8000 This enables the timeout and sets it to 8000 milliseconds (= 8 seconds). By default the timeout is not set, so wait infinitely.
