This should be

location  /first {
    echo   "before";
    echo_location_aysnc  /second;    (or echo_location  /second)
    echo  "after"
}

location    /second {
    set   $memcached_key   $uri;
    memcached_pass   127.0.0.1;
}

The reason is to do with how the internals of Nginx work.  Everything 
that has echo_XXX should follow in order.  If you try mixing echo_xxx 
statements with other directives, you'll likely get *interesting* results.

Cool.  If you haven't done so already, it might be useful to add it to 
any of the other echo_xxx directives that automatically add a newline 
(e.g. echo_before, echo_after ?) - if it's not too much trouble, of course.
