In my current maildir mailbox, I have some messages[*] with big Cc
(several hundreds of addresses). When I want to move to the page
of the index where these big messages appear, Mutt hangs for a few
seconds (taking CPU time) before displaying this page. The strace
contains something like:

The hangs is due to this big Cc and the "subscribe" / "lists" commands
in my muttrc.
Is this hang expected or could the efficiency be improved?
This may be a corner case, but note also that spammers can send similar
messages.
[*] The cause here is:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=776073;msg=20
(the Cc doesn't appear in this message, but another message has been
is generated by the Debian BTS as a consequence of this one).
