It can return on unix signals, so you have to test for EINTR.
I don't think it will wake up unexpectedly otherwise.

I'm thinking of rewriting the whole ITC object so it uses a
futex instead of the CV (that would also enable it to work
in shared memory across process boundaries), but then I really
need a lock free implementation for the linked lists. 
I guess the required primitives are platform dependant.
Is their some library that provides them ?
