# This test checks that omprog restarts the external program when it
|
|
# terminates prematurely, and that it does so without leaking file
|
|
# descriptors. Two cases are checked: termination of the program when
|
|
# omprog is going to write to the pipe (to send a message to the
|
|
# program), and when omprog is going to read from the pipe (when it
|
|
# is expecting the program to confirm the last message).
