Re: poudriere: swap_pager: out of swap space

indeed, i was, because this is how sysutils/htop displays memory usage:

top(1)

Mem: 8502M Active, 15G Inact, 1568M Laundry, 5518M Wired, 1343M Buf, 690M Free

htop(1):

  Mem[||||||||||||||||||||||||||||||||||||||||||                          13.7G/31.9G]

i'm vaguely annoyed, but also not surprised, to find out that htop is
wrong here...

so, how are Inact pages created?  does this happen from filesystem
writes, or something else?

is there somewhere this that is documented?
