I have a HUNK which points to an array containing hunks, and theses
hunks point back to the top hunk, and also to arrays which contain
hunks that point back to the top hunk.
=> I swear I can show that arrays are not getting garbage collected
Storage is not getting reclaimed, and I run out very fast this way
on a pdp-10. I almost think I'm crazy reporting that the maclisp
garbage collector doesn't work. Please tell me it isn't so.
I believe you. It can require multiple GCs to reclaim arrays linked
cirularly. This is a known problem not easily fixed, and I have some
mail stashed away from several years ago detailing the problem in depth.
It would be interesting to know if the arrays NEVER get reclaimed, or
just require several GCs to be reclaimed.
