I noted that Emacs (emacs --daemon) takes a lot of of CPU (up to 80%), even
when I am not using it. I am starting emacs --daemon from my ~/.gnomerc, which
is invoked when I start my X session.

I used strace to see what was going on:

gettimeofday({1265471350, 42334}, NULL) = 0
read(0, "", 4096)                       = 0
write(2, "Back to top level.", 18)      = 18
write(2, "\n", 1)                       = 1
poll([{fd=7, events=POLLIN}], 1, 0)     = 0 (Timeout)
gettimeofday({1265471350, 42538}, NULL) = 0
read(0, "", 4096)                       = 0
write(2, "Back to top level.", 18)      = 18
write(2, "\n", 1)                       = 1
poll([{fd=7, events=POLLIN}], 1, 0)     = 0 (Timeout)
gettimeofday({1265471350, 42736}, NULL) = 0
read(0, "", 4096)                       = 0
write(2, "Back to top level.", 18)      = 18
write(2, "\n", 1)                       = 1

[...]

and this continues at high speed. Apparently, emacs calling the lisp function
normal-top-level in lisp/startup.el many, many times.

Hope this helps tracking down the issue.

Best wishes,
Dirk.
