--- Comment #9 from Konstantin Belousov <kib@FreeBSD.org> ---
(In reply to Pedro F. Giffuni from comment #8)
Could you, please, read some code instead of commit messages, before coming
with conclusions ?

The sizing of exec_map is scaled with number of cpus.  It is already pared =
down
on ILP32 due to KVA exhaustion issues.  Even if we assume that the bump is =
from
4M to 8M (which is not), it is already quite sensitive for low-KVA machines.

On my low-end (8 threads but amd64) desktop machine, I have ~17M reserved f=
or
the submap.
