Hrm.. I'm using memcached on my laptop w/o any problems.  The only 
problem I have is terrible kqueue(2) performance on OS-X, though I'm 
starting to get the impression that Apple crippled this system call on 
their non-server OS versions.  But, I don't need to tweak anything to 
get it running.  What OS version?

Use bzero(3) instead of memest(,0,).  bzero(3) is always going to be 
faster since most OSes provide asm optimized verions of said call.

bzero(&addr, sizeof(addr));
