200MB of resident size sounds a bit large.  Of course, it complely depends
on what you do with it.  Now that you mention it, I also see it here (my
main Emacs process is at more than 600MB of RSS).  Interestingly, I don't
see it with my Emacs process running Gnus (it's at 45MB of RSS).  Both of
them were started on June 6.

The 600MB process reports the appended info, which doesn't seem to justify
its size (even if you mutliply all the data by 2 since this is a 64bit
system and I'm not sure if the memory-report tool correctly takes it into
account).
