User context is when you are coming in from a system call or
other trap: you can sleep, and you own the CPU (except for
interrupts) until you call <function>schedule()</function>.
In other words, user context (unlike userspace) is not pre-emptable.

"Next the statesmen will invent cheap lies, putting the blame upon
the nation that is attacked, and every man will be glad of those
conscience-soothing falsities, and will diligently study them, and refuse
to examine any refutations of them; and thus he will by and by convince
himself that the war is just, and will thank God for the better sleep
he enjoys after this process of grotesque self-deception." -- Mark Twain
