Could it be that msync(2) is called over that mappings ? Try this
diff --git a/sys/vm/vm_object.c b/sys/vm/vm_object.c
index fa197214296..33e7e6f8643 100644

Bug 222356: www/firefox: file-backed shared memory performance
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=222356
--- Description ---
Created attachment 186420
--> https://bugs.fre
Firefox 57 gained[1] more U2F support in Firefox 57. It relies on
u2f-hid-rs[2] which hasn't been ported to FreeBSD.
I'm not sure if Chromium supports U2F on FreeBSD but if no one helps
Firefox won't as well. Note, U2F Support Add-on doesn't work in FF57.
