You might want to take a look at DBIx::Sequence, which does a similar thing to what you want in a vaguely cross-platform way.

From the pod...

This module is intended to give easier portability to Perl database application by providing a database independant unique ID generator. This way, an application developer is not bound to use his database's SEQUENCE or auto_increment thus making his application portable on multiple database environnements.

This module implements a simple Spin Locker mechanism and is garanteed to return a unique value every time it is called, even with concurrent processes. It uses your database for its state storage with ANSI SQL92 compliant SQL. All SQL queries inside DBIx::Sequence are pre cached and very efficient especially under mod_perl.
