When using datasource programs, e.g. for checking by SSH, the Check_MK process could be terminated by a reached timeout leaving the launched subprocesses open. This might have caused in processes being too long open, running and consuming resources.

The datasource program process and it's sub processes are now cleaned up when a check timeout occures.
