The blocking executor's start() method functions as a request processing
loop - i.e. it blocks, processes messages and only returns when stop() is
called from a dispatched method.
Method calls are dispatched in the current thread, so only a single method
call can be executing at once. This executor is likely to only be useful
for simple demo programs.
