The problem is that the forked thread will be blocked too as long as
the main thread is blocked by XNextEvent.

In xmobar Spencer came up with a version of XNextEvent that doesn't
block in a foreign call, so that it can be interrupted by an
asynchronous exception. This is not going to be feasible in xmonad,
unfortunately.
