Slight adjustments to the poll() loop
Recheck the entry at the current index after we remove one. This isn't strictly necessary, since the next pass will get it anyway. Using a vector as opposed to our own realloc()'d array means indexing beyond the size() is undefined behavior, so it's better to be safe.
