Signals are not queued.

As far as I know, there is only one piece of one Unix manual that
claims otherwise (that being the System V SIGCLD documentation), and it
lies.  Signals are never queued.  System V SIGCLD signals use a
different trick that causes properly-coded wait routines to be called
once per exited child, but which causes improperly-coded wait routines
to recurse indefinitely.
