<antrik> braunr: do you have any idea what could cause the paging errors
long before swap is exhausted?
<braunr> antrik: not really, but i know every project based on the mach vm
have rewritten their swap pager
<antrik> (and also I/O performance steadily dropping before that point is
reached?)
[[performance/degradation]], [[ext2fs_page_cache_swapping_leak]].
<antrik> hm
<braunr> there could too many things
<antrik> perhaps we could "borrow" from one of them? :-)
<braunr> map entry fragmentation for example
<braunr> the freebsd one is the only possible candidate
<braunr> uvm is too different
<braunr> dragonflybsd maybe, but it's very close to freebsd
<braunr> i didn't look at darwin/xnu
