Sure. The worker process is single-threaded. And by using blocking
calls in the content handler essentially turns nginx into an apache
server with the prefork mpm. Some inexperienced nginx developers have
been making such serious mistakes in their nginx modules.

Just use nonblocking calls and leverage the nginx event model. You can
check out all those nginx upstream modules out there, ngx_memcached,
ngx_redis2, ngx_memc, ngx_drizzle, ngx_postgres, ngx_proxy, ngx_lua,
ngx_beanstalkd, and etc etc etc.
