Cought.
Attached is a change that implements a fixed 30 minute timeout for a single 
test.
The change was initially a port of your code snipped. The difference in the 
implementation arises from signal.signal not willing to execute in a non main 
thread.
I expect that in the long term one needs a per test configurable timeout. Also 
probably a time factor that is put on that numbers for the valgrind runs.

Greetings
