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 :]
