Hi folks...

I'd like to make the SOSEND_LOAN option (which uses page loaning to achieve
zero-copy TCP transmit) the default in -current, and add a new option,
SOSEND_NO_LOAN, to disable it.  The code has been in -current for a while
now, and several people have been giving it a good work-out.  It makes a
significant difference on platforms which are short on memory bandwidth.
