This happens only after at least one call to the action server. On Ctrl+C, the executions gets stuck on the final rospy.spin() until SIGTERM signal is received. It happens both with tabletop and tod detectors, so I think the problem is in the underlying ecto infraestructure. Another clue on this is that it seems to be a problem with a destroyed thread/mutex, and tabletop don't use threads at all (afaik):
terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::lock_error> >'

[tabletop_object_recognition_server-7] escalating to SIGTERM
I tried also to manually handle the Ctrl+C signal as in here; surprisingly enough, it also scalate to SIGTERM but some times with different message:
[tabletop_object_recognition_server-7] escalating to SIGTERM
[senz3d-4] escalating to SIGTERM
[tabletop_object_recognition_server-7] escalating to SIGKILL
[rosout-1] killing on exit
[master] killing on exit
Shutdown errors:
* process[tabletop_object_recognition_server-7, pid 370]: required SIGKILL. May still be running.

The non-server version of tabletop doesn't have this problem, but it calls the ecto cells in a completely different way (at least it seems so to me!).

Puzzling....
