If I push a hard workload of large (2MB, containing 136x1000 array) documents into a standalone wiredTiger - I get very slow performance, stalls and very long drop() times (minutes) with wiredTiger - up to 60s long stalls on occasion.

That's with 3.0.7

In 3.2-rc0 I do not see this at all - is this a known issue and is it being backported to 3.0?
