Ok, but a) why can't the list of unpacked revprop files be cached at startup and updated as revprops are edited. If this is too much trouble, b) why not write a list of edited revprop files to a single file instead - this option may not help that much, but would at least keep the 'index' file in the OS fs cache and would prevent checking the disk for lots of revprops when returning log history and the like (ie the system would only need to read those files that you know are there, removing the need for stat calls)
When svnsadmin pack is run, the cache, file, or table would just be wiped so there's little maintenance required - you will need to rename or delete the unpacked shards as the pack operation runs, or prevent read and writes to revprops during this operation.
