Sounds reasonable in that I would not expect a garbage collection problem
related to circular references to be fixable using the technique you
describe. But I can't explain how that technique could possibly be working
at all.

loops are lexically (my) scoped - though this also defies logic.

As already suggested, an 'exit' is a very good way to initiate garbage
collection. Maybe you could schedule an exit and restart every hour or so,
since it's impractical to have an exit and restart every 5 seconds. The
Win32::Process module provides a convenient way of handling such an
