spawnPIDf won't with applications that take arguments, for example:
spawn "xset -b"
I think the best solution is to add an 'exec' to your spawned applications:
spawn "exec xterm"
This is the shell's syntax to execute a program directly rather than fork.
The current implementation seeks to balance all of these concerns:
* users want to supply arguments to programs
* users will find "spawn prog [arg1, arg2, arg3]" syntax unwieldy
* we don't want to support a homebrewed argument tokenizer in xmonad
* some users will want to use shell syntax in their spawns
