--- Comment #8 from Konstantin Belousov <kib at FreeBSD.org> ---
I also wrote the promised procctl(PROC_STACKGAP_CTL), see
https://reviews.freebsd.org/D21352. But I do not think that it would alone
help with the JVM use of guards. It might be needed in addition to e.g. use
mmap(2) before mprotect(2).
