At some point the decision was made to use true/false as a return
value for most of the socket functions. This value is generally
redundant. Typically Lua functions will return nil, error_message for
recoverable errors and the expected values otherwise (which gave rise
to the assert function). I believe if we make any change we should
move away from these useless boolean values. Alas compatibility is a
concern here.
