test-fcntl is not the only test that fails:

$ cat test-fcntl.log
FAIL test-fcntl (exit status: 42)

$ cat test-execute.sh.log
test-execute-main: test-execute-child subprocess failed

This indicates that all processes inherit many open file descriptors
(at least, all from 4 to 19). This explains the failures.

Nothing to worry about.
