The catalog is kept in .catalog-cache in the library, each entry with the size and modified time of the file it was read from; a start takes the entries whose file is unchanged from it and reads only the rest. It is saved once the catalog is complete and has changed (at most every 30 s) and at shutdown. After a reboot the catalog was complete 145 ms after launch, against 3.5 s reading every file. The catalog loads on the background Thread_Group, every worker of it, instead of the four preview workers. rpmalloc (modules/Default_Allocator, 2.0.1-jai.16) takes the place of Jai's single locked heap: entries from the cache 380 -> 50 ms, and reading the files now scales with threads. thread_idle is called where workers idle. check_targets.jai checks other OSes with Jai's own allocator, as rpmalloc runs at compile time with the target's OS layer. -cold drops the library from the system's file cache first; -no-catalog-cache and -catalog-threads N are for measuring. [startup] log lines time the listing, the first frame, the cache, the first preview and the complete catalog.
