swap
NAME
swap - swap out a file explicitly
SYNOPSIS
void swap( object );
DESCRIPTION
This efun should be reserved for debugging only. It allows an object
to be explicitly swapped out. If enabled, it is strongly recommended
that a simul_efun override (for this efun) be used to prevent abuse.
Note: objects which have been destructed, already swapped out, contain
a heart beat, cloned, inherited, or interactive, cannot be swapped out.
