From what I hear, this is may or may not be a good thing. The view
maintains a queue of lock/unlock calls so you can lock it as many times
as you want in one thread, but I'm a bit nervous about the situation
where one thread is interrupted inside a drawing call with an
-unlockFocus call from the secondary thread. May I suggest that simply
from a conceptual point of view, no two threads should ever share a
view. For safety's sake, I suggest either putting a healthy number of
locks around the view or simply not share it between threads.
