[xmonad] xmonad and launcher prompt memory

[Carsten Mattner]

Carlos,

I'm wondering whether using the launcher prompt may be the reason
for xmonad starting at 4 to 5 megs freshly and climbing to around 7 megs.
I didn't try without the launcher promot and don't really complain but
am curious whether there's some caching and possible space leak
in either the launcher prompt or xmonad core or one of the popular
action hooks.

Gwern, this is not an objection to merging, just an observation.

This is on ghc-7.6.1-i386.

Any comments?
