It appears that the shell simply aborts on fork failure. Example:

peter ~$ cat test.sh
ulimit -u 30

for i in $(seq 1 25); do
echo $i
( sleep 5 ) &
echo ok
done

wait
echo "all done"
peter ~$ sh test.sh
1
ok
2
test.sh: fork: Resource temporarily unavailable
peter ~$

In pg_regress, the big loop is probably done in a subshell, because it's
in a pipe, so the outer script can complete. Detecting failures in
commands in a pipe is of course a bit tricky.
