src_prepare() {
	# xmobar is an idle multithreaded program
	# which sits in 'while { sleep(1); }'
	# loops in multiple threads.
	# It has a pathological behaviour in GHC:
	#   everything program does is thread context switch
	#   100 times per second. It's easily seen with
	#
	#       $ strace -f -p `pidof xmobar`
	#
	#   where rt_sigreturn() manages to enter/exit
	# kernel 32 times in each second to do nothing
	# This workaround allows shrinkng wakeups/thread
	# switches down to one per second (internal xmobar's
	# cycle).
	# Be careful when remove it :]
