Change Item 10, Clarify Execution Preference, p. 22

Replace item 5 with the following text:

5. Instances of the NoHeapRealtimeThread class may have an execution eligibility higher than any garbage collector. If the garbage collector executes in the context of a thread with a higher execution eligibility then the instance will block because the RTSJ honors execution eligibility first. However, unlike instances of java.lang.Thread or RealtimeThread, the instance of NoHeapRealtimeThread will not be blocked by the garbage collector executing in the context of a thread with a lower execution eligibility.
