/**
 * Provides synchronization between breakpoints set from outside of the Eclipse
 * breakpoint framework (GDB console, trace files, etc.) and the Breakpoints
 * view.
 * <p>
 * Bug 530377: Prior to fixing 530377, events that arrived from GDB faster than
 * DSF/Eclipse fully processed them could cause the state within the
 * synchronizer and manager to become corrupt. This would happen because it
 * takes multiple DSF stages to complete handling 1 event, so the handling of
 * the next event would become intermingled. That violated many assumptions in
 * the code that the code run in the respective RequestMonitor would be on the
 * same state. This is an unsuprising assumption based on the general idea of
 * DSF as not requiring the normal synchronization primitives as everything is
 * single-threaded. To resolve this problem, there is some code
 * {@link #queueEvent(BreakpointEvent)} that ensures each event is fully
 * processed before the next event starts processing.
