I tested it on 3 machines running XP SP2, as a normal user on 2 of them
and as admin on 1. It doesn't have to be a specific program, I can copy
notepad.exe and name it install, and when it terminates, explorer.exe
consumes CPU for a short while (less than a second).

It becomes really obvious if I run something like this in Cygwin's bash:

for i in `seq 1 100`; do /usr/bin/install --help; done

or in the windows command prompt (cmd.exe):

copy \windows\system32\help.exe install.exe
for /L %i in (1,1,100) do @install

and watch the explorer.exe process in the task manager. It is strange if
it doesn't happen for you, maybe I need to investigate this further. I
don't like this behavior.
