Tx denis.

I wonder what is the reason of the crashes I experienced.

I don't know. Here is details on covered issue:

TestExecutionEnvironment introduces problem when image is saved inside test process (which is case for Guille code which fork image inside test).��

And problem is that snapshot restarts all low level processes like IdlProcess, eventLoop and others (which are spawned in startup list). And when it happens inside test process all child processes are intercepted and terminated when test completes which means killing all system processes on test completes

To fix it image snapshot should be always performed under default execution environment. (There is already another case like this: opening debugger to debug test. Debugger spawns new UI process and it should not be under test environment).
