--- Comment #16 from Vladimir Druzenko <vvd@FreeBSD.org> ---
So, we have come to the conclusion that now (MAXCPU=3D1024 by default) ther=
e is
very little point in creating any patch for emulators/virtualbox-ose-kmod?
Therefore, I propose to simply close this PR as an Overcome by Events.

IMHO, we should think about the next increase MAXCPU before release 15:
- Intel has had CPU [1] for over a year now that allow to create a server w=
ith
960 threads (60 cores per socket * 2 threads per core * 8 sockets);
- AMD just announced [2] a CPU with 192 cores per socket * 2 threads per co=
re *
2 sockets =3D 768 threads.
So even before the end of life of 14, servers with the number of threads > =
1024
may appear.
