If you look at the perforce logs, you'll see it was in libutil at
first.
While I like libutil for some single functions (I added
humanize_number(3) in there), but I don't like putting there
everything.

In my first concept (when it was part of libutil) I allocated memory
to store needed informations, because I didn't wanted to use preallocated
memory (someone linking libutil doesn't have to use pidfile
functionality).
Now, when it is a small library I can use preallocated memory and
eliminate one point of potential failure.
It also now has 4 functions, which makes it a good candidate of small,
nice, lightweight library:)
