User's code can create several short-living external arrays that could occupy a lot of memory. Even if all references to the objects are cleared the external arrays may not be collected for a long time until the major GC. We may want to change the way GC is triggered to take into account size of external array data.

On the second look it seems that the GC is triggered just at a higher threshold.
