The engine internally limits the number of functions reported back (to 16 by default). To this point, it's been sort the profiling info in *ascending* order of time spent, then trimming the list. This meant we may only see the best (fastest) functions, instead of the worst that you probably want when profiling. Now the servers_debugger sort more closely matches the local_debugger one, which worked fine.
