#528 Zombie process

[Carlos Falcon]

I saw some Pool and MS "zombie" process (e.g. The same Pool PoolName executed several times). I reproduced it time to time executing the sardanatestsuite, or when I killed the MS with control+C.

I use Tango 9.2.2 and PyTango 9.2.0 installed via zypper from http://download.opensuse.org/repositories/home:/cmft/openSUSE_13.2/
