Resyncing a 40k folder generates 380k mail_addr_is_user calls for 5mn (try 3)
[mmmh, my mails still look like they're randomly getting eaten. Trying one
more time]

I don't think that's it.
When I open my 40,000 message Sent folder, it takes maybe 5sec.
after opening mutt:
magic:~$ wc -l .muttdebug0
1462 .muttdebug0
magic:~$ grep -c 'mail_addr_is_user:' .muttdebug0
211
after going to Sent folder:
magic:~$ wc -l .muttdebug0
124381 .muttdebug0
magic:~$ grep -c 'mail_addr_is_user:' .muttdebug0
427
I send an Email, it gets added to my Sent folder, and wait 5mn for mutt to
resync:
magic:~$ wc -l .muttdebug0
723660 .muttdebug0
magic:~$ grep -c 'mail_addr_is_user:' .muttdebug0
380841
So, that's almost 10 mail_addr_is_user per mail in the inbox, and each takes
almost 0.0008s, which yields 300 seconds for 40,000 messages.
First, it looks like mail_addr_is_user is a pretty slow call, but it's also
weird
that it gets called so many times.
Hopefully that helps pinpointing the problem.
