If locally written applications are running the system out of swap space, they can change storage from malloc()/new (make space on the VW which is backed/rolled out on swap) to files attached with mmap() or the JAVA equivalent. The files in mmap are used as backing store, so all RAM is there to cache the access, but no swap is used. Reading and writing are just memory accesses. If an app crashes, the data from RAM pages will be written by VM, which can help debugging. This not only reduces swap space usage, it reduces swap traffic.

Glib::Flags(3)						User Contributed Perl Documentation					    Glib::Flags(3)

NAME
Glib::Flags DESCRIPTION
Glib maps flag and enum values to the nicknames strings provided by the underlying C libraries. Representing flags this way in Perl is an interesting problem, which Glib solves by using some cool overloaded operators. The functions described here actually do the work of those overloaded operators. See the description of the flags operators in the "This Is Now That" section of Glib for more info. HIERARCHY
Glib::Flags METHODS
scalar = $class->new ($a) o $a (scalar) Create a new flags object with given bits. This is for use from a subclass, it's not possible to create a "Glib::Flags" object as such. For example, my $f1 = Glib::ParamFlags->new ('readable'); my $f2 = Glib::ParamFlags->new (['readable','writable']); An object like this can then be used with the overloaded operators. scalar = $a->all ($b, $swap) o $b (scalar) o $swap (scalar) ref = $a->as_arrayref integer = $a->bool ($b, $swap) o $b (scalar) o $swap (integer) integer = $a->eq ($b, $swap) o $b (scalar) o $swap (integer) integer = $a->ge ($b, $swap) o $b (scalar) o $swap (integer) scalar = $a->intersect ($b, $swap) o $b (scalar) o $swap (scalar) integer = $a->ne ($b, $swap) o $b (scalar) o $swap (integer) scalar = $a->sub ($b, $swap) o $b (scalar) o $swap (scalar) scalar = $a->union ($b, $swap) o $b (scalar) o $swap (scalar) scalar = $a->xor ($b, $swap) o $b (scalar) o $swap (scalar) SEE ALSO
