Some systems (e.g. OpenBSD) have a rather small default socket send buffer
size of 4KB. The result is that sending requests with a largish payload
requires serveral writev(2) system calls. Make sure the socket send buffer
is at least 64KB such that we're likely to succeed with a single system
call for most requests. A similar change was made to the xtrans code
some time ago.
