I upgraded to 1.7 and am having this crash happen with some of my bigger collections. It appears that in the code there is a cursor on all the items in a collection, this ends up hitting a timeout and crashing.

Is it really necesary to query the entire collection in this package? This is probably a meteor bug, but it should be possible to work around.

I was looking around at other forks of this, and saw this that might be a solution to fix this problem, but I don't have nearly enough knowledge of this package to know how to test it or if this would even work
