[xmonad] spawnOn in startupHook only works for one Nemo window, not the other

[Brandon Allbery]

This is a symptom of "factory windows". spawnOn can't work for them, you
need to find out the application-specific way to attach distinct
identifiers to windows, because _NET_WM_PID will never match for any but
the first window opened (and sometimes not then). And no, neither spawnOn
nor any similar mechanism will be able to find a "fix",, because
"application specific" — and even then not every application bothers to
provide a mechanism to label specific windows.
