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.
