It's cat and the scheduler. You have two processes fighting over stdin.
cat inherits stdin, and successfully reads one character, because its
read returns successfully before readline's pselect returns indicating
that there is input and readline calls read.
cat tries to write the character to an invalid fd (the pipe is gone), gets
-1/EPIPE/SIGPIPE, and dies in the background.
Readline calls read and successfully reads the next character.
