Sorry, I think I had amended line length in some of the earlier patches then forgot with the later patches - will check those again.

Thanks, I'll amend that.

Mainly because on systems with a several network interfaces, this can result in the function call taking a long time, due to the delays enforced by the WSD/SOAP specifications. Sending messages simultaneously on several threads speeds this up considerably. On Windows the API appears to return near-instantly so I presume it's doing the same.

A thread pool would likely be sensible but I'd prefer not to rewrite this code again at present if possible.

Thanks,

Owen
