seems that the collapser is too eager; you can test this with:

\ctxlua {
	callback.register('vpack_filter',     nil)
	callback.register('buildpage_filter', nil)
}

i fixed it, but this is one of the areas where testing is needed;

next on my agenda is to implement an extended vertical spacing model; 
actually it is already active, but we need a higher level interface, like:

\defineblank[mine][category=1,priority=5,skip=10pt,penalty=10000]

penalty
	largest wins
priority
	highest wins
categories
	discard
	only if larger
	force even if smaller,
	only take penalty component
	add to existing skip

by combining skips and penalties this mechanism provides much more 
control over page breaks
