beware of having enough contiguous virtual memory in your process.
We had troubles on WinXP in situations of highly fragmented VM, since
the TCP/IP stack needs to allocate the entire message as a single chunk
before sending it. Breaking a large message into multiple sends would
be ok, but unfortunately the standard OmniORB TCP/IP transport does it
in a single send.<br>
