If either of the tests fails unexpectedly due to a bug in
eventd-related code then the absence/presence of child processes, which
we get from the pstree output, will help to debug the failure. For
example, if the 2nd test fails but only shows the event script process
(but not the sleep) then that tells us that there's something wrong
with script cleanup. With just ps we don't get that extra hint.

peace & happiness,
