Status: RESOLVED FIXED

(Core :: JavaScript Engine, defect)

Attachment: clean up on shrinking GCs

We have a special GC mode for "clean up everything". However, it's not getting triggered for shrinking GCs. This patch fixes that.

Attachment: don't hang on to small exec pools across GCs

Right now we hang on to small executable pools forever. This drops our references to them after every GC.

Adding a direct slim-fast dependency so this is easier to find.  Thanks a lot for looking into this, Bill!
