6136f11 make container a subclass of reactor and remove redundant code
which is replaced by reactor
severely broke the dispatch system tests. I haven't looked into it yet
but my best guess is they broker the SyncRequestResponse class that is
used by the dispatch tools and hence by most of those tests.
I will investigate, if anybody else sees anything please let me know.
Apart from fixing the issue we need to improve the tests for that class
in the proton build (that would be my fault.)
