Squid running check

I noticed that squid checks if it is running by checking if pid file
exists. I think it will be better to check if there is really process
with that pid like:

if(kill(pid,0)==0){//squid is running

}else{ // no process
   //unlink the pid file
}

I don't know how kill is implemented in other operating systems but I'm
sure that there is a way to check if process is running.
