This is a Lua system that removes the power to create/destroy Location/Group/Force/Rect after 0.01s passed. This time was choosen to allow creating new Objects in Map init triggers. Instead when the map's code would request a new object of such types, then it cycles a fixed set of such. It mostly is meant for GUI users.
Installing this will remove Leaks of this types, but it also breaks code that depents on creating many new objects in one run.
Like this Trigger will break when one installed this system, because Loc will be moved to some other place when the Location object-Set Size is surpassed on default when the group contains 4 or more units:
ChangeLog:
1.1 can now choose default amount of objects inside Leak preventer with a number, increased default to 64, mentions the Enable/Disable Feature in the head comment.

-- Leak Preventer 1.1a By Tasyen
do
--[[
gui Location/Group/Force/Rect functions that would create new objects won't anymore. Instead they move/reuse a fixed amount of objects.
variables created in InitGlobals (variable editor) are unaffected until overwritten by a "new" object.
this version replaces only the creators, hence it is quite small
one can turn of Leak Preventer by executing trigger udg_LeakPreventerDisable
one can turn on Leak Preventer by executing trigger udg_LeakPreventerEnable
if you want to use this feature in GUI you need to create trigger variables for them.
