I have found
this thread, which might help you and contains pointers to some additional sources.
I have never encountered a problem like the one you describe because there is a certain data type in C (pid_t) in the system header files. There should be no range problems if you use it. If someone wouldn't use it this would be extremely bad programming style and i wouldn't expect such a hack in a standard software (you mentioned Oracle).
Of course, nothing is really impossible, so maybe you have a point here, however unlikely. I'd appreciate it if you could tell us your findings once your investigation is completed.
I hope this helps.

uri::heuristic5.18
URI::Heuristic(3) User Contributed Perl Documentation URI::Heuristic(3)
NAME
URI::Heuristic - Expand URI using heuristics
SYNOPSIS
use URI::Heuristic qw(uf_uristr);
$u = uf_uristr("perl"); # http://www.perl.com
$u = uf_uristr("www.sol.no/sol"); # http://www.sol.no/sol
$u = uf_uristr("aas"); # http://www.aas.no
$u = uf_uristr("ftp.funet.fi"); # ftp://ftp.funet.fi
$u = uf_uristr("/etc/passwd"); # file:/etc/passwd
DESCRIPTION
This module provides functions that expand strings into real absolute URIs using some built-in heuristics. Strings that already represent
absolute URIs (i.e. that start with a "scheme:" part) are never modified and are returned unchanged. The main use of these functions is to
allow abbreviated URIs similar to what many web browsers allow for URIs typed in by the user.
The following functions are provided:
uf_uristr($str)
Tries to make the argument string into a proper absolute URI string. The "uf_" prefix stands for "User Friendly". Under MacOS, it
assumes that any string with a common URL scheme (http, ftp, etc.) is a URL rather than a local path. So don't name your volumes after
common URL schemes and expect uf_uristr() to construct valid file: URL's on those volumes for you, because it won't.
uf_uri($str)
Works the same way as uf_uristr() but returns a "URI" object.
ENVIRONMENT
If the hostname portion of a URI does not contain any dots, then certain qualified guesses are made. These guesses are governed by the
following environment variables:
COUNTRY The two-letter country code (ISO 3166) for your location. If the domain name of your host ends with two letters, then it is
taken to be the default country. See also Locale::Country.
HTTP_ACCEPT_LANGUAGE, LC_ALL, LANG
If COUNTRY is not set, these standard environment variables are examined and country (not language) information possibly found in
them is used as the default country.
URL_GUESS_PATTERN
Contains a space-separated list of URL patterns to try. The string "ACME" is for some reason used as a placeholder for the host
name in the URL provided. Example:
URL_GUESS_PATTERN="www.ACME.no www.ACME.se www.ACME.com"
export URL_GUESS_PATTERN
Specifying URL_GUESS_PATTERN disables any guessing rules based on country. An empty URL_GUESS_PATTERN disables any guessing that
involves host name lookups.
