Segmentation fault if inappropriate function used for trigger

[pgulutzan]

I have Ubuntu 12.04 and Tarantool 1.6 pulled from source today.

I execute these requests:

box.cfg{}
box.schema.space.create('T')
box.space.T:create_index('primary',{})
box.space.T:on_replace(os.exit)
box.space.T:replace{1}

The result after 'box.space.T:replace{1}' looks like this:

tarantool> box.space.T:replace{1}

Peter, please document this (you already did). We could make os.exit work, but overall Tarantool stored procedures code is runing in unprotected environment, you can do whatever you want, including shooting yourself in the foot.
