Greetings all; Despite asking repeatedly what was the largest count a maildirs index file could have, I've never been graced with an answer. But my inbox has been reimported as new installs took place over the years so that from 2002 to now there were quite a few messages carrying a file system date for Feb 5 thru Feb 6 2015, despite many of them carrying arrival dates in their headers that were much earlier, clear back to 2002. So just for S&G, I just moved all those to inbox subdir, killed the indices and restarted kmail. Initial blast of rebuilding indices, then settled to the bottom of the htop list. Maybe I was onto something, so I did the same thing with an even higher count of messages dated Feb 6 2015. Stopped, waited 30 secs and restarted kmail, good 45 secs to start as it did those indices new. But settled to bottom of cpu usage in another minute. Then to preclude any confusion about the years, I renamed the around 18 year only names for emc to emc-year, killed those indices and restarted kmail. Wash, rinse and repeat on restart. I have one more set of subdirs in the coco folder named only for the year, so I'll do the same thing there so they are named coco-year. I think I've found it.
