Bug description: gethostbyname is not interruptible by signals
Description:
------------
gethostbyname() is not interruptible by signals. If it cannot resolve an
hostname there is no way it can be interrupted except for a SIGKILL.
Reproduce code:
---------------
declare(ticks=1);
function al($sig)
{
echo $sig;
exit(0);
}
pcntl_signal(SIGINT, "al");
pcntl_signal(SIGTERM, "al");
pcntl_signal(SIGALRM, "al");
pcntl_alarm(3);
echo gethostbyname("google.com");
Expected result:
----------------
I was expected to interrupt gethostbyname() with any signal.
Actual result:
--------------
When running the above code, if the system cannot resolve google's
hostname, the function blocks and doesn't respond to any signal.
