Subject[PATCH][TRIVIAL] don't let OOM killer kill same process repeatedly

If a process cannot exit because it's stuck in eg. a driver, it
doesn't make sense to have the OOM killer kill it repeatedly;
that could lead to a hung system.

Instead, kill another process if the first process we tried to
kill hasn't made any move to exit within 5 seconds. This way
we have a much better chance of recovering the system.

Note: this patch applies without offset to both 2.4 and 2.5,
since oom_kill.c hasn't changed since about 2.4.14...

please apply,

Rik
