yeah, i just figured that out.  i'll just patch our wicket for now.  but we
should add this for wicket 1.4 (in a nicer way than this (generic utility
method), of course):

                                                final StringBuilder builder = 
new StringBuilder();
                                                StackTraceElement[] elements = 
t.getStackTrace();
                                                for (int i = 0; i < 
elements.length; i++) {
                                                        
builder.append(elements[i]);
                                                }
                                                throw new 
WicketRuntimeException("After " + timeout + " the Pagemap "
                                                                + pageMapName + 
" is still locked by: " + t
                                                                + ", giving up 
trying to get the page for path: " + path + "\nStack
Trace: " + builder.toString());
