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).
For trapped signals, yes. Bash wants to catch other signals of interest
(e.g., SIGINT) and handles those during shell processing -- just not in
a signal handler.
