It's getting EOF from the closed pipe that triggers xmobar to exit. If
xmobar isn't reading from the pipe, it won't notice the EOF.
You could still do it, just use a dummy StdinReader and write a single
newline down the pipe after opening it.
bottomBar <- spawnPipe "xmobar ~/.xmobardownrc"
hPutStrLn bottomBar ""
(Since it's an empty line, the StdinReader won't take up any actual space.)
