 I can't repeat this with libpthread (it's no longer libkse).
 
 -bash-2.05b$ gcc -Wall -o kse_test kse_test.c -lpthread
 -bash-2.05b$ ldd kse_test
 kse_test:
         libpthread.so.1 => /usr/lib/libpthread.so.1 (0x2807a000)
         libc.so.5 => /lib/libc.so.5 (0x2809d000)
 -bash-2.05b$ kse_test
 -bash-2.05b$ echo $?
 0
 -bash-2.05b$ ps -ax | grep kse_test
   712  ??  S      0:00.02 kse_test
   698  p1  I      0:00.85 nedit kse_test.c
   727  p1  D+     0:00.02 grep kse_test
 -bash-2.05b$ kill -INT 712
 -bash-2.05b$ ps -ax | grep kse_test
   698  p1  I      0:00.85 nedit kse_test.c
   729  p1  S+     0:00.03 grep kse_test
