You aren't kidding re: ARM is a very fragmented architecture to
support. As you can imagine, "toolchain" is usually among the foremost
inter- and intra-office discussions. More than it needs to be IMHO.

It's possible that it's not. I just looked and I believe we were
possibly (stronger, probably) not targeting the correct processor.

If time permits I shall. For now I am going with a "simpler"
client/server socket implementation. It's a little closer to the
socket itself, for what we need to get done.

Willing to admit, possibly not. I don't think it's that complicated. A
certain amount of faith I am putting in the io_service scheduling its
call backs, etc.
