How often is this flush executed, and what percentage of the corresponding progress indication is never sent to a terminal? Flushing can be expensive (very, even), and *could* be part of what delays build/upgrade commands for ports that have a lot of dependencies (the VM in question takes almost a minute to check all dependencies of port:kde4-workspace before it starts fetching/extracting/patching/etc).
