syntax for changing httpd socket_options on the fly

[Dave Benson]

I'd like to set "nodelay" on our couchdb -- but i haven't found a syntax
that works.

    curl -X PUT http://localhost:5984/_config/httpd/socket_options -d
'[{"nodelay": true}]'

(the most obvious thing) gives a
   {"error":"unknown_error","reason":"badarg"}
response.

ideas?
