*) Feature: now the $upstream_status and $upstream_response_time
variables keep data about all upstreams before X-Accel-Redirect.
*) Bugfix: a segmentation fault occurred in master process after first
reconfiguration and receiving any signal if nginx was built with
ngx_http_perl_module and perl did not support multiplicity; bug
appeared in 0.5.9.

reconfiguration perl code did not work; bug appeared in 0.3.38.
