What happened to System/Process.getPid() ?

I was half-planning on implementing getPid back in 2008 but ran out of time.

My intent was to have the pid simply be a String, even though on common
platforms an int would suffice, leaving enough room for unusual
implementations to get what they want.
Essentially, return in String form what humans would use to identify
processes on the machine, which might be e.g. "NODENAME:NNN" on a cluster.
