I remembered that request that right after I replied and had a similar
thought.

True.
But perhaps some more usefull ideas could be derived from this. Use a
sed/awk/perl command to build up a menu that has function calls and
passing in the found filenames, for things like:
- a menu of background files (and the function invokes xv on them).
- to get all of the modes from the current version of xlock
dynamically so you don't have to update your menu every time a new
version comes out.
- a list of files in a directory that you freqently edit to pop them
up in your favorite editor (perhaps XEmacs & gnuclient to put them
into your currently running XEmacs).

Ah. Hadn't thought about that...
I wonder how difficult it would be to implement a solution to that.
Like an Exec variant that puts it into the background so we don't lock
up fvwm, but monitors the child to see if it's still alive and have a
Wait variant that waits for the last Exec'd child to finish. I'll
have to look into something like that.
