swapcontext.c fails because the threads were killed inside of nanosleep
STEPS TO REPRODUCE
OBSERVED RESULT
``` runqemu kvm
valgrind --tool=drd --read-var-info=yes --check-stack-var=yes
--show-confl-seg=no --num-callers=2 ./swapcontext

==277== by 0x36C74C8726: nanosleep (nanosleep.c:25)
==277==
==277== For lists of detected and suppressed errors, rerun with: -s

```
EXPECTED RESULT
i think the test should pass because it generated 0 error.
the nanosleep is called inside of f
