Hm.  I'm a little puzzled by the continued appearance of the "no job
table entry" warning but this --

} #15 <signal handler called>
} #16 0x00007fff896dad62 in tiny_free_list_add_ptr ()
} #17 0x00007fff896d9e7f in szone_free_definite_size ()
} #18 0x000000010365e89a in inputsetline ()

-- is another case where we're manipulating global state without blocking
signal traps.
