deleteById commitWithin question

[Jamie Johnson]

I am running off of a snapshot taken 5/3/2012 of solr 4.0 and am
noticing some issues around deleteById when a commitWithin parameter
is included using SolrJ, specifically commit isn't executed.  If I
later just call commit on the solr instance I see the item is deleted
though.  Is anyone aware if this should work in that snapshot?
