Could be, but for tens of minutes?
AFAIK gc_sweep shouldn't cause too much thrashing either (the sweep is
a mostly sequential scan of memory, so even if the total heap is larger
than your total RAM, it should be ~O(total heap size / bandwidth from
swap partition)), so I can't imagine how we could spend tens of minutes
doing gc_sweep (or maybe the time is spend in gc_sweep but doing
something else than the sweep itself, e.g. handling weak pointers, or
removing dead markers from marker lists, ... still seems hard to
imagine spending tens of minutes, tho).
