Reminds me of a resource serialization problem I had back in the old uni days, where I had to synchronize data between parent/children.

One of the solutions was to use an external database, where database I/O's were handled by an independent (external) process.

Another solution was to use shared memory (I was coding it in C then). I think it must be our liz who has posted this module on CPAN (well done liz) - forks::shared. It states that:

The "forks::shared" pragma allows a developer to use shared variables with threads (implemented with the "forks" pragma) without having to have a threaded perl, or to even run 5.8.0 or higher.

And example pulled from CPAN -
use forks; use forks::shared; my $variable : shared; my @array : shared; my %hash : shared; share( $variable ); share( @array ); share( %hash ); lock( $variable ); cond_wait( $variable ); cond_signal( $variable ); cond_broadcast( $variable );
Take a look at this module, I think this might be a more elegant solution to your problem.
