I was thinking about this ticket today. Regarding Alan Bateman's comment
that the pid may not be representable as an int/long, I was expecting some
sort of Pid-like-object to be returned. I'd rather see an abstraction that
*might* be able to convert into an int/long ... or even a String, as Martin
B. just said.
