On a system conforming to POSIX.1-2001, you just can. The easy solution would be to call sigaction with the SA_NOCLDWAIT flag, but System.Posix.Signals lacks the interface to do this :-(.

So would the right thing be to improve that module and throw a conditional flag into xmonad to use it?

Absolutely. However, it's wired into the RTS, so I just opened a ticket -- http://hackage.haskell.org/trac/ghc/ticket/3980. Since we're trying to maintain compatibility with older GHCs, I'll submit a patch with "a silly wait-loop handler" shortly. Regards, -- Tomáš Janoušek, a.k.a. Liskni_si, http://work.lisk.in/
