Agreed, sched.h contatins a lot of garbage, including the signal bits.
As for signal_struct in particular I am not really sure, it is just
misnamed. It is in fact "struct process" or "struct thread_group". But
dequeue_signal/etc should go into signal.h.
The only problem, it is not clear how to test such a change.
Oleg.
