History
alc c123c7433b When the swap pager allocates space on disk, it requests contiguous 
blocks in a single call to blist_alloc().  However, when it frees
that space, it previously called blist_free() on each block, one at a
time.  With this change, the swap pager identifies ranges of
contiguous blocks to be freed, and calls blist_free() once per
range.  In one extreme case, that is described in the review, the time
to perform an munmap(2) was reduced by 55%.
