I haven't looked at the Bash code thoroughly, but IIRC, Bash basically
uses `sigaction ()' and also basically just raises flags in a bit
vector in the signal handlers. The actual handling of signals is
mainly done in ``trap handlers'' (which Bash implements and are
invoked by Bash between the execution of shell commands).
