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.

I've now bound `process-connection-type' to nil in `rgrep' for Emacs 24.
