File locking GSoC task: Update exercise suggestion

While the suggestion is certainly good as an exercise, it is probably
not suitable for producing an actual patch quickly. Warn about this, and
explicitely mention that finding a different task might be necessary.

 Exercise: Find one of the existing issues, either by looking at the task/bug
 trackers on savannah, or by trying things out yourself; and take a go at it.
-Probably you wont' be able to fix the problem in a limited amount of time, but
-you should be able to do a detailed analysis of the issue at least.
+Note though that most of these issues are probably not trivial -- it's quite
+likely that you won't be able to actually fix any of them in the time available
+during the application process. However, you might be able to spot something
+else that could be improved while looking into this.
+
+If after trying for a while you haven't found anything easy enough to improve
+in the locking-related code, talk to us about some alternative exercise task.
+Perhaps you actually find something you could do while looking through the bug
+tracker or trying stuff yourself in search of locking issues :-)
