Steve Hoelzer e8dfcace31 poll: use GetTickCount64() to avoid wrap-around issues ... The value of timeout starts as an int value, and for this reason it cannot overflow unsigned long long aka ULONGLONG. The unsigned version of this initial value is available in orig_timeout. The difference (orig_timeout - elapsed) cannot wrap around because it is protected by a conditional (as can be seen in the patch text). Hence, the ULONGLONG difference can only have values that are smaller than the initial timeout value and truncation to int cannot overflow.
