Nix seems to use XFT builds primarily right now. I see the same behaviour on
a non-KKCC build with server-side fonts--my solution so far has been:

derrick [ cat ~/bin/unlimited-xemacs
#!/usr/pkg/bin/zsh
ulimit -d unlimited
ulimit -c unlimited
exec /usr/local/bin/xemacs $*

but that’s a long way from being the Right Thing. On the TTY build I
normally use for reading mail, it leaks, but not as badly: 

    VSZ  RSZ
  44604  39m 

with 20078197 as the show-memory-usage output. (I have an RSS ulimit of
46080K there, however, so opening a decent-size mailbox gives me an
out-of-memory error.) This means the leaking is not X11 specific. 

I don’t use KKCC in general, because it has been less responsive for me than
the old GC. If I remember correctly, however, its summaries of memory usage
were more accurate, to some extent.
