ghci: 20 wakeups per second
From http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=438371 :
According to powertop on my laptop, ghci seems to wake up 20 times per
second looking for input when sitting at the command prompt. This has
negative impact on battery life, as discussed on the powertop page.
I don't think the change in the HEAD to using timer_create
rather than setitimer
will have fixed this, but I can't currently run powertop so haven't been able to confirm that.
