Works fine for me, I get 172 matches every time.

That's just waiting for the grep to finish, which is fine.
I'm not sure why your function is so complicated. Instead of doing a
separate grep for each directory and then combining them, why don't you
do one big grep for everything? Append "/*.el" to each element of the
directory, concatenate them, and pass them to grep. E.g. if load-path
contains ("/path/to/dir1" "/path/to/dir2") you do
(let* ((paths (mapconcat '(lambda (dir) (concat dir "/*.el"))
load-path))
(command (sprintf "egrep -nH -e '%s' %s" regexp paths)))
(grep command))
