The true evil approach is to send the socket around, not the message, so that there is no copying required no matter what ;)

Wah. Easy there, Satan :-)

That is cool trick though. So it's basically sending the port itself around and changing its ownership, with something like port_connect(Port,NewOwner)?

The trick is more commonly used when writing to sockets. A socket owner is required for reading, not for writing.

The trick then is that when you need to write lots of data to a socket to just send a copy of it to the writer so they can dump all their data for cheap, but without changing ownership (which is costly).

Also recently I've gotten http://propertesting.com/ out, you might enjoy it :)

Thanks for explaining. I'll have to remember the socket trick.

It might be just what I need to understand and start using property tests. I've tried twice and gave up.

Oh and recon! Thanks for that too. Use it almost every day.
