We used the named pipes for a while in our setup. I saw syslog using up 
30% cpu time on our quadcore 1950 dells (2.6 Ghz intel) when pushing 
them to max load.

Later I wrote a patch which you can find it here 
http://article.gmane.org/gmane.comp.web.nginx.english/5296. This patch 
disables the use of named pipes, but performance with syslog is just as 
bad. The bottleneck isn't nginx offcourse but syslog.
