I don't think it is possible to achieve the request queuing
functionality without modifying Nginx's source.  The patch is a small
change and does not affect how other modules work - it would be nice
if it could be merged.

It adds a new return value, NGX_BUSY, for the peer.init() callback in
upstream modules. In the case of this, the module can itself decide to
when to call ngx_http_upstream_connect() - until then the request
hangs.
