emacs -Q -nw
M-x rgrep RET emacs RET *.el RET PATH_TO_EMACS_SOURCE_TREE/lisp RET

takes a few minutes.  The output is about 9000 lines.

Running the correspondind command:

find . \( -path \*/SCCS -o -path \*/RCS -o -path \*/CVS -o -path \*/MCVS -o -path \*/.svn -o -path \*/.git -o -path \*/.hg -o -path \*/.bzr -o -path \*/_MTN -o -path \*/_darcs -o -path \*/\{arch\} \) -prune -o -type f \( -name *.el \) -print0 | xargs -0 -e grep -i -nH -e emacs

from a shell (and redirecting the output to a file) takes less than one second.
