Unuse resources after every test

Fix bug in put_all(). That method was unused before this commit.

Clean the process list after the processes are stopped,
otherwise the suite eventually fails with a 'process terminated
prematurely' error. Before it was not necessary because it was not
reused (a new suite run was created).
