Linux2.6 overcommit behaviour

Hi all,

Following is from Documentation/vm/overcommit-accounting
-------------
2    -    (NEW) strict overcommit. The total address space commit    for the system is not permitted to exceed swap + a
  configurable percentage (default is 50) of physical RAM.    Depending on the percentage you use, in most situations
this means a process will not be killed while accessing    pages but will receive errors on memory allocation as
appropriate.
-------------

Looks like it's been taken care once for all.
