The program can testify bindresvport() is multithread-unsafe

Steps to Reproduce:

# gcc -o bindresvport -lpthread bindresvport.c
# while true; do ./bindresvport 2>&1 | grep 1024; if [ $? -eq 0 ]; then break;
fi; done
port = 1024

The program output the bound port, valid value is 512 to 1023. if the bound
port is 1024, bindresvport() is multithread-unsafe.
