Konstantin Belousov 245139c69d Fix OOM handling of some corner cases.
In addition to pagedaemon initiating OOM, also do it from the
vm_fault() internals.  Namely, if the thread waits for a free page to
satisfy page fault some preconfigured amount of time, trigger OOM.
These triggers are rate-limited, due to a usual case of several
threads of the same multi-threaded process to enter fault handler
simultaneously.  The faults from pagedaemon threads participate in the
calculation of OOM rate, but are not under the limit.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
