I suspect that a more viable long-term solution is to modify Perl proper to manage the level of parallelism provided by multi-core processors, perhaps by binding something like Linda or MPI to Perl (another task for the Perl 6 developers).

I tend to think that a better long-term solution is to incorporate parallelism into the language, as is done with languages such as Fortran-M. Yes, I know that Fortran is considered horridly outdated, but there has been a lot of effort in modifying Fortran to minimize the onus upon application programmers of developing programs which use parallelism.
