We now record all notifications from all pathways in a central location: ~/Library/Application Support/Growl/Saved Notifications. That directory contains one subdirectory per day, and each of those subdirectories contains plist files which are named in the pattern “Growl saved notification #NUMBER.plist” (where NUMBER increases monotonically from 0).

Naturally, this is restricted to the main thread, in order to avoid two notifications from different sources running into each other in attempting to save their respective notification files.
