[Raleigh-talk] Parallel::ForkManager and progress

I've got a long running batch process that uses Parallel::ForkManager to split the work up and take
advantage of the multiple CPU/Cores on the box. This part works fine (have I mentioned how much I
love P::FM?). But I'd like to have some sort of a running progress on the screen when run manually.
So, any ideas on how best to do this? Since each worker is a separate process I could use something
like Net::Shared or IPC::ShareLite to collect stats that are then reported on. Anyone have any
success with these modules or have recommendations on shared memory modules?
I've also thought about using the database to store the progress. That has the benefit of being
something I can query even if the process isn't being run manually. But it has the drawback of
having to connect to the database (which won't be on the same machine) and sending it lots of little
queries to update a couple of counters.
