The C runtime for POSIX includes a clock() function that gives you the  
amount of time that your process has actually had on the CPU. I’ve  
googled for a way to get access to this from Ruby, and all I get is  
the fact that rubyprof uses this in its implementation. Is there a  
way to get at this or something equivalent from Ruby without having to  
write a C extension?

Thanks.

Process.times ?
