So, a few days ago, I posted this: -
about a problem that I was seeing with kernel_task taking >80% CPU on my Mac, whilst running OS X 10.9.1.
For me, quitting iTunes appeared to resolve the problem.
Then, earlier this week, Apple released OS X 10.9.2 to resolve a problem with the so-called Goto Fail bug.
This was also supposed to resolve the problem with kernel_task, and, I must admit, I've not seen that since.
However, I have seen a few issues with the Mac failing to properly resume from suspend ( in other words, wake up when I open the lid ).
Well, the Mac Crash Reporter did pop up earlier today, with this: -

This came up after I'd had to power on the Mac, as it was failing to awaken ( I didn't try and kiss it; perhaps I should've done so ?? )
I've sent the report off to Apple, let's see what happens :-)
