Make Go program set its cpu priority

Hi,

In some perl programs sometimes I made a call to set priority, to lower my program's niceness so it would hopefully yield to other things on the system if it bad behaved. Can go do this? A search of http://golang.org/search?q=Setpriority makes it look like it is unimplemented.

It looks like it's in "syscall" for darwin and the bsds. You could probably rawsyscall it on linux as well. Like daemonizing a go binary, however, it seems like this is the sort of thing you should do externally, e.g. in the script that starts your daemon. I believe some of the newer start-stop-daemon tools (and their friends as well can set nice levels as well as things like I/O scheduling priority.
