Forgot to mention that the "post subrequest" handler does not get
called in this case. It seems ngx_http_upstream does not call
finalize_request. Most likely an issue in ngx_memc's input filters.

If others can take a look at the ngx_http_memc_empty_filter_init and
ngx_http_memc_empty_filter functions in ngx_memc below, I'll really
appreciate that:
