Posix requires this behavior.
"When the shell is waiting, by means of the wait utility, for asynchronous
commands to complete, the reception of a signal for which a trap has been
set shall cause the wait utility to return immediately with an exit status
>128, immediately after which the trap associated with that signal shall be
taken."
