[erlang-questions] how to flush a gen_tcp socket on close?

Hi,

gen_tcp sockets do buffer sends internaly. It seems, when
calling close on them, the buffered data is not flushed out,
but simply discarded .
I was expecting that a close on an socket with outstanding
send data would block until that data has been send, but that
seems not to happen. In fact, that might be a bug????

So, how do I force a gen_tcp socket so flush it's send queue
before closing it?
