Use larger join timeout window\n\nas on some machines it seems to take a little bit more time then one second to spin a process down
do not count SyncManagers towards active children left running on shutdown
Merge branch 'master' of https://github.com/trbs/bucky
make join timeout configurable and have metricsd server join its child processes
add timeouts to tests so that they will not hang forever
execute each test suite in its own nosetests command which seems to be a workaround against the problems we are having with python3 and the tests
