# A 2MB heap is to analyze most web pages. For the outliers, we need to either

# allow for heap growth, or allocate an unreasonable amount of memory at the

# outset.

# Unfortunately, once the heap has been enlarged, there is no shrinking, so

# analyzing one 20MB web page gives us a 30-40MB heap for the life of the

# worker.
