A testcase

"expect" is needed to reproduce this bug. I am
using expect-5.39.0-98 from Red Hat. I got

# nohup make&
# ps -xa
...
 2770 pts/0    S      0:00 make
 2771 pts/0    S      0:00 time expect test.exp
 2772 pts/0    S      0:01 expect test.exp
 5985 tty1     Ss+    0:00 /sbin/mingetty tty1
 8146 ?        Zs     0:00 [true] <defunct>
...
# tail nohup.out
count: 1786
spawn true
count: 1787
spawn true
count: 1788
spawn true
count: 1789
spawn true
count: 1790
spawn true

on a UP P4 HT running SMP kernel. UP kernel is OK.

It looks like an expect bug. I will close it for now.
